Originally I was more wanting terminal since there are so many more options as far as places to go. With that said that leaves more places to be stuck that I wouldn't necessarily want to go to either. After talking to people on here as well as seeing the locations of centers I realized I didn't really care which I got, terminal or center. Ultimately I got an en route TOL so it didn't matter in the end.
To answer your question though, centers pay more up front from what others have said. They both seem to have their pros and cons as with any job, but it's all about what you want from the career.
