Odd, this is the first mention of the topic in a few weeks or more (in General Chat, at least). I think many of us have voiced our options at one time or another, and I'm not sure they've changed since the last time it was brought up.
I do know a number of Xbox Minecrafters who were quite put off with the state of the Better Together Update, but most of them simply went back to playing the pre-update version (since the update was actually a new game that downloaded, not really updating the original) and carried on like it never happened. They won't be able to play cross-platform, but their worlds aren't a buggy mess this way, and they're ok with that tradeoff until the state of the BTU is on par with what they were already using.
