@alexzhu I'm in the same boat. I've been looking at several alternatives, particularly those that look and feel Windows-ish to make the transition (hopefully!) easier. I've settled on ZorinOS, as it looks slightly easier to install than Mint Cinnamon and better looking than Q4OS. As far as I can see Vivaldi should be ok on all of them. Also Zorin has abandoned Firefox as its default browser in favour of a simplified Brave (all the fancy dan BAT stuff disabled).
Good luck with your weekend!
