I'm enjoying it more than I did F4, honestly, but that's partly because I really really hated the "build and support villages" aspect of F4.
Outer Worlds is well written and funny space romp with rather little roleplaying (you have seemingly tons of options, but often the results only affect the next dialog line and the game is so easy that the player quite often can pass any skill test) while Atom RPG is dark, hard and bleak post-apocalyptic role playing game where almost any situation can play out in so many different ways depending on your skills and luck. Atom RPG is Fallout 1&2 worship to its core, with all of the flaws of the original 2 included.
I am not saying that Outer Worlds is objectively a worse or better game, it's just different.
