PKD is one of my favorite authors. Nobody before or since has been able to more accurately capture the slippery nature of reality, in my opinion.
I very much enjoy PKD’s writing, though he gets hard to follow in his later stuff as he slipped further into drug abuse and mental illness.
However, it's better, because of the sheer power of the visuals and worldbuilding. Some things in it have not aged well (like the "love" scene), but it is still simply jaw-dropping. It's what Scott is just unmatched at doing. A villeneuve film probably makes more sense, but Ridley Scott does Ridley Scott better than anyone. Give him a good script and watch him fly.
They're both excellent, they don't need to compete. Be glad 2049 ever got made (similarly with Dune really).
Now, do I think it needed a sequel? No.
