I'm going to miss Set Measure/Beat at Now badly if and when I'm forced to abandon SONAR. 
I'm with you. I will not be giving up Sonar. I've owned Cubase, Digital Performer and Logic and Sonar just fits the way I work (and my MIDI needs) better than any of them (Cubase is pretty close). I tried Ableton, Studio One, DP, Cubase, and Reaper after finding out about the closing of Cakewalk and none of them impressed me in a big way. I really thought that I might be able to get along with Studio One because its user interface is really quite good, but it has two fatal flaws that are complete show stoppers for me. I use external MIDI equipment extensively and Studio One has no way to load patch names for the literally thousands of patches my equipment has (right there it meant I would not be using Studio One), but in addition, when you create a MIDI track, no corresponding mixer controls appear in the mixer. You have to pop up a 'universal' midi editing panel to change volume, pan, etc. I saw workarounds posted saying I should just use the volume control for the audio input that the midi device is plugged into, but that is a fail too. I always have multiple patches playing through that single external MIDI device. One volume control just doesn't hack it. Cubase is actually better than Sonar in this respect since you can actually load categories such as 'keyboard', 'guitar', 'bass', 'percussion' for the external MIDI patches.
I gave up on Digital Performer after just a few minutes because the font size is so small I'd be spending every minute using the program squinting to read things. I was unable to find any Preference setting to change the font size.
If I ever find that I 'have' to move on, it will almost certainly be Cubase even though (and probably also because) it is very expensive. You usually get what you pay for...
