I really don't have a favorite quest, considering I finished all of the F2P quests back in RSC when they were still a bit challenging (Well, just Dragon Slayer lol) but I have no idea which one was my favorite.
I'm actually thinking along the lines of Recipe for Disaster, it was funny, fun, challenging, and annoying, and took awhile. It also forced me to gain levels which of course helps overall no matter what
I'd say that one was my favorite until further notice (never know, Jagex may release a quest I like better than RFD).
