Switching DAWs in order to experience fewer bugs is an exercise in futility. All you'll do is trade a set of deficiencies you know about for a new set that you haven't discovered yet.
Switching DAW vendors in hopes of finding one that's more responsive to user requests, now that's a legitimate mission. Cockos certainly qualifies in that regard. But Steinberg? If you think they're a user-centric business, you haven't been following their history. Cakewalk still ranks among the best in terms of communication with users, even if it's not as good as it once was.
Switching DAWs because you need a higher track count, that's a real possibility. Objective benchmarks do seem to support the claim that Cubase is more efficient than SONAR, and that Reaper is more efficient still. No benchmark can ever establish this with certainty for all conditions, but the numbers do generally suggest that Cubase may indeed manage higher track counts.
Personally, I just don't get the obsession with DAWs. For me they are just a means to an end. Pick one and learn it well enough that it doesn't get in the way of making music.
