Reading about a Thunderbird version for Android got me exited, because I am a big fan of the desktop version (actually, I donated a few bucks this week). However, on Android I used K9 for years, until I noticed how unreliable it became. I switched to Outlook and it is okay.
When I saw that the Thunderbird app will be based on K9, the excitement vanished instantly. I really hope they will invest into the reliability issues. Judging from the play store comments, it could be worth it.
I don't know when you used K9 for the last time, but it has improved in stability greatly in the last ~two years. It's true that some years ago it went downhill for a while.
