POE2 is a slog, bosses take 10-15 minutes and are able to 1-2 shot you at times. Melee classes are fucked, the gameplay is extremely slow and the endgame is pure cancer.
Diablo IV is faster, can reach the endgame in a couple of weeks, get your seasonal items and stop playing and more importantly it's fun to play. It also looks better and has no microsutters.
POE is gigashit and will always be.
