Mentions suck on Amethyst. You have to search for people prior to tagging them for them to work. Damus uses nostrdb and is fantastic with fast and easy tagging.

Got it. Damus seemed to have focused on making the core experience as solid as possible, the other features will come, if needed.
I client hop a fair bit to try stuff. But I always come back to Damus. It just feels more zen
Anytime I try compose a new note and tag someone on Amethyst my app just crashes lol.
