Using ThumbKey’s “english thumbkey words symbols” layout along with circular gestures for upper / lower case letters and numbers I can reliably score 60 words per minute on MonkeyType. I also don’t need to look down on the keyboard to type, so personally I love it.
With that said, if your free time is limited and you also type on a variety of languages, switching to ThumbKey may not be worth the effort since a lot of languages have their own layouts.
Personally I don’t see myself switching away from ThumbKey, but it’s kind of a vim vs nano situation. I think Traditional T9 will be the happy medium for most people in this case.
Firefox can’t even export bookmarks, so when Mull got deprecated I had to move my hundreds of bookmarks manually to Cromite. It sucks that people whose phones are still on Android 8 are stuck with that thing.
