Notably back when Diablo III was still fresh, lots of people suggested PoE. To me, D3 felt more of an arcade-like game that I can quickly jump into and have fun, whereas PoE is more of an efficiency and numbers game. Like it's fun, but I just don't have that sense of being "powerful". I gradually progressed up until Act 5 in PoE (before they added Acts beyond that) and never really felt like I was all that powerful. There were some challenges here and there, but most things just died in some boring manner.
However with Diablo II as I recall, that's pretty much the same ordeal up until a certain point.
I may re-visit PoE at some point this year before D2:R to see if or how things have changed.
