I tried liking KF2 but it just lacks the crispness and the atmosphere of KF1. I also missed the shop lady with her opening shop in the weirdest locations in between rounds. So yeah, KF2 lacks charm IMO and I still like KF1 more even on its aging UE2.5 engine. I don't think KF3 will find my interest, with all the multiplayer games going "live service" and all.
