in poe2 it is completely possible for a brand new person to the game to start playing, pick a skill, develop it into a build, and use that build to complete all of the existing content in the game, all without watching any streamers, youtube videos, or looking at any guides. this hasn't been realistically possible in poe1 for a decade.
even if you prefer the sandbox nature of poe1, it's hard to argue that poe2 is a better designed and more complete experience for MOST PLAYERS than poe1 is at this point.
