I heard a streamer describe it as while PoE2 looks harder combat-wise, there is a lot less hidden mandatory knowledge and building so it's more approachable.
PoE2 has more punishing mechanics, combat is more active and you need to dodge enemy attacks, and bosses reset HP if you die. But you don't have the same checklist of things you need to be viable, and there's less focus on knowing the mathed out optimal setups since support gems are now focused on changing skill behavior rather than providing multiplicative damage boosts.
