I love my console 1 and had a few gripes about how it integrated with SPLAT - that is  until I tried the VST 3 plugin.  Wonderful communications - track names, pans, volumes.... all controlled with the C1 in SPLAT.  I had no idea.
 
Now I am wondering what I have missed in my countless other plugins.  For the most part, I never installed the VST3s because I thought that was a Qbase thingy and just ignored it.
 
Now I am at least partially seeing what I have missed.  Of course, I got Melodyne in VST3 so I could do the clip effect thing.  
 
What wonders are out there awaiting a soul brave to sail the VST3 seas?  Or is it still novel?

The experience varies but in general if provided you should definitely install and use the VST3 version of plugins. While many plugin vendors just use standard VST2 features under VST3, there have been various extensions to VST3 that some plugins take advantage of. Console One is such an example but there are many others that use VST3 specific features such as Softube, Waves etc.

I agree completely with Noel's comment. It is rare these days that the VST3 version of a plugin is not as solid as the VST2 version, so you should use it be default.

I haven't had any trouble with VST3 for a long time now. I think they are very stable. 

I jumped on the VST 3 train as early as possible (back when Cakewalk first introduced it).
And I have been happy ever since. Never really had any issues at all.

I'm so happy with VST3 I can hardly wait to see what VST4 does.

dang it.  now i need to go back and figger what i have that has vst3s.  
 
 
thanks for opining y'all all.  

well my most used plugins are not vst3!  UAD, Soundtoys....arturia.  dang

I wouldn't do a total reboot just to install any VST 3 plug ins you have. VST 2 is still great. 
Just don't be afraid to install them in the future.

oops - arturia is vst3!  but not my other faves!
