4e was the first pen and paper d&d I’d played. I liked it.
I spent far more time creating characters for it than I actually played it. It was really fun to create characters for.
Combat was a slog though (pre Monster Manual update days). 1 action with usually a 50% to 60% chance of working also meant many turns you did nothing (I guess some powers had miss effects or granted multiple attacks but yea).
Roleplaying was there but even more than long combats, the idea of really balanced but ultimately winnable encounters seemed to detract some from roleplaying choices really mattering.
I had fun with 4e and still like building characters for it more than for 5e but I like 5e better overall. I would still play a 4e game if a dm wanted to run it.
