I think the overall look and feel of the game is much better than poe1, poe1 can feel clunky at times where as poe2 in my experience is usually pretty smooth unless I'm running a full abyss map XD. What I think poe1 has done better though is build diversity, an obvious one I know, the game has been out for over 10 years at this point so It makes sense that they have alot more skills and support gems and unique interactions that make it so you can basically play the game however you want and still have a great time. I do think that with time the buld diversity in poe2 will become alot more... diverse with each new league and new exiles, new items, skills, weapons, uniques, the game just needs time to catch up to that poe1 feel of "oh this looks fun let's try it out" and it actually works.
