Long time Sonar user here, from version 7, 8, 8.5, X1, X2, X3 and now Platinum.
 
I recently purchased a PreSonus StudioLive AR16 USB Mixer to do multi-track recordings for band practice. That got me into using Presonus Capture and the free version of Studio One. I was blown away by how easy Studio One is to use and how STABLE it seems to be.
 
I'm now running the full demo version of Studio One and so far it seems to be rock solid and a real joy to use. The arranger and scratch pad features are very useful and could be a game changer for song writing.
 
So far with Studio One: no audio drop outs, no clicks, no pops, no crashes. After using it for a few days I opened a Sonar project and got a click and audio drop right away. Sonar runs about 85% stable for me (if I had to pick a number).
 
So the question is... any advice on whether the switch is worth it? So far there doesn't seem to be any compelling reason to stay with Sonar (unless the stability issues are resolved). It seems that rolling updates have destabilized the product.

I don't have any stability problems with Sonar Platinum and I've been upgrading every month.  You have been very vague in your post but normally issues like that are caused by hardware or third party plugins. 
 
But you need to use the tool that works best for you. 

Here's the thing I don't get. Why does it have to always be "switch to" or "dump" or any other such thing. It's not like Splat will suddenly be rendered inoperable because you installed another DAW on your system.
 
I currently use two DAWs regularly. SPlat and Reaper. I mostly stay in SPlat for creative process stuff (writing, tracking, mixing) and for more hardcore engineering tasks that SONAR isn't as good at (intensive wave manipulation, intricate tempo mapping and I'd likely use it if I were to track a full live band due to it's low resource footprint).
 
This method serves me VERY well and in fact made me much happier with Sonar. The only thing that made me REALLY cranky in the past was when I needed to perform a specific (and often times extremely laborious) task and the Sonar projects would slowly become more unstable (because I was pushing it too hard in a direction the program did not want to go). Now when that seems likely to happen for a specific phase of my projects I do the work in Reaper then drag the files back into Sonar when it's done.
 
Also, if I had the money I'd definitely try to acquire other DAWs so I could have access to features/workflows specific to those programs (as well as for curiosity's sake and compatibility with other studios if they request it).
 
So my answer is...

I didn't want to make a long drawn out post, but as I said, I'm a long time user of Sonar without any real problems until Platinum. I'm running an Alienware, i7, 16 GB with a Scarlett 2i2 second generation.
 
If plug-ins are the culprit, then there must be something in Studio One that handles it better than Sonar does.
 
I have a friend with a brand new machine who is constantly battling bugs between the rolling updates, it's because of him that I really started to take notice of all the problems in Sonar that I've been ignoring or dealing with. Stability issues seem to be well documented on the forums. I'm sure there are many happy users out there, and I was one of them. It wasn't until I started to check out another product that I saw what I was missing.
 
I had better results using my old M-Audio FastTrack Ultra 8R than with the new Focusrite Scarlett, but Studio One works fine with both.
 

So you are asking a forum set up for and populated by Sonar users whether you should switch to a competitor?
 
Well... okay then. Have fun with that.

Beepster, your comment about intricate tempo mapping in Sonar is relevant for me. If I work in 12/8 things can get really wonky for me. Clip end times will render incorrectly, way past their true end point, the background grid isn't rendered properly, blocks are inconsistent in their size.
 
Why not both? Perhaps. But I don't see me keeping up with both products. I believe future Studio One releases are free, whereas Sonar works on a paid subscription type model.

Beepster, I was just trying to open up a conversation about my experiences to see if I could gleam any knowledge or insight from others out there. I've already heard some decent feedback from you on this, and I appreciate that, but based on how people tend to behave online, perhaps you're right, I may be poking a bear here.
 
As I've said, I've been using Sonar for 10+ years. I've loved it, defended it and recommended it. I've recorded 5 full albums with it.
 

Use what works for you. I have both Studio One and SONAR Platinum, and use them for different things.
 
I don't agree that rolling updates have destabilized the product.

I just got a 6i6 2g. Had infrequent glitches. Focusrite tech support worked it through with me.
Turned out my bios was not set up correctly. And, I read that net adapters are often at fault. I use a wireless adapter when I go online, so I had disabled the net adapter in devman, now disabled in bios as well. Much improved. 
I rolled back to an earlier display driver, fewer glitches. 
Then, I switched th 6i6 from a usb 2 port to usb 3, and that made all the difference on my system. 
My point is, maybe sonar is more "sensitive" than studio one, but in my case, making system-level tweaks made glitches in sonar go away. Sonar was telling me something was wrong… 
 
 

The question of staying or leaving is an interesting one, because it's not just based on performance and workflow issues, but emotional ones as well. There is loyalty, for example. I use Sonar 8.5, never made the jump, because it was so drastic that I realized it was essentially learning a new DAW. Which made me look at other DAWS. Which resulted in me eventually settling on Reaper. But I have not left sonar 8.5 behind. I like some of the tools, esp. mastering; and besides all my projects were begun in sonar, and sometimes I need to open them to look at how I did something; or import something, etc. So I will definitely still use it some. and last but certainly not least, this forum is an incredible resource. I need the wisdom that lives here! So my advice: Don't leave. Loosen the strings a bit perhaps, but don't cut them. The old "don't close any doors" thing is very good advice!
