What an interesting topic! I haven't tried filejungle yet but their pps-fixed plan looks inviting. At the same time I like Wupload because Willy really provides a very good support for uploaders (nicest support in my opinion), plus, he seems to be drowning in the cosplay thing (you can see a picture of a Gorilla reading a book with glasses posted by Willy in one of the pages of Wupload support thread). I bet Willy dig his character a lot.
