What I miss so far in Studio One.

Step Sequencer and Matrix View were so broken in Sonar that I gave up on them long ago, but maybe things improved recently?
 
The lack of Track Templates in Studio One is mildly annoying; I work around it with a combination of larger song templates and FX Chains. In practice it's not been as much hassle as I'd feared.
 
Lack of gain knob was mildly irritating but it's trivial to increase the gain on a clip (drag the handle at the top) and if that isn't enough, I add an EQ as an insert and just adjust the overall output gain.
 
Event Editor... never used it in Sonar except to look in vain for rogue events that might have kept it playing past the end of the song...  so not sure what an S1 equivalent would be.
 
Mix Recall - no equivalent as far as I know, sorry.
 
Groove clip - if you need to copy a loop, hit D to duplicate it. If you need to stretch it, hold Ctrl and drag the end (or Alt - I forget). Studio One also supports some sort of loop format and I expect you can convert a clip to that format if you really need the drag-to-repeat functionality? (Not sure though.)
Clip property information in Sonar Inspector window - does the Studio One Inspector not show what you need?
Special copy paste - I used this in Sonar because non-special copy/paste was worthless. What in particular do you need from this?
Link Clips - hold Shift and press D to duplicate a clip in 'shared' mode.
Waveform preview for instrument tracks - yeah, not sure there is an S1 equivalent. Maybe after 'convert to audio track' but that's basically bouncing it.
Alt+click a bus track to select all tracks routed to that bus - not sure about this. There's a little indicator somewhere in the console view showing how many tracks are routed in there, so maybe clicking randomly on that with shift/alt/ctrl might do something ;)

Yes, the gain knob...just click on the bottom part of an audio clip and it will highlight in light blue.  You'll see a gain adjustment handle on the top center and adjust your gain there.  You can do that to multiple clips at a time, dice up and clip and do very detailed clip gain adjustments.  Super fast and easy.  You can also toss the MixTool plugin on any channels you like if you want an actual knob.

Well, according to this:

S1 does have Note Chase...

Thanks for the link Dan. I just got SO3 and that was helpful for the other info there as well. Right now, the hardest thing to get used to is the start at now time that Sonar has. All I've found so far is Alt P that will start back at the selected place and you have to turn that off and on and click to a new place for playback to start and  again hit Alt P.
 
Hopefully there's something I'm missing here.

You are missing reconfiguring your keyboard shortcuts. All of those things (like RTZ) are available commands. You just need to assign them to the keys you want to use. However, before you go crazy and reprogram something you might actually want once you get used to SO, on the keypad, press:
 

• KEYPAD ENTER = Starts Playback
• KEYPAD * = Start Recording
• KEYPAD + = Fast Forward (Add SHIFT to jump by measure)
• KEYPAD - = Fast Rewind (Add SHIFT to jump by measure)
• KEYPAD 0 = Stop Playback
• Press KEYPAD 0 again to return to where playback started.
• Press KEYPAD 0 a third time to RTZ.

 
It's pretty easy to get used to it. You can also download the free remote control app for iOS/Android tablets and all of those are buttons in the app...
