You read my mind, as i was just asking myself the same thing. I have recently been thinking of switching over to bitwarden from classic keepass...but now i see keepassXC, and wondered what - if any - compelling feature/need that keepassXC brings...?
p.s. - Oh, and the reason for considering even moving to bitwarden is ease of mobile access by several people at once...since schlepping a keepass database via file sync stuff works sort of ok until you have to access the same file via mobile (possible but not great), plus my family and i kept stepping on each other's toes when updating said file, etc. Not hating on keepass, as it has served my family really weell...and i'm very thankful to the keepass devs! It is simply that we might be outgrowing it a tad...maybe.
