I still haven’t seen AOTC, I really should try to watch it.
I would watch a fanedit. If you’ve truly never seen the theatrical you might be able to actually enjoy it, but you are pretty much guaranteed to not like the theatrical.
I was considering the exact same thing when I went for my very first viewing of The Phantom Menace, but in the end I did go with the official Blu-Ray version (not DVD because puppet Yoda in TPM sucked). This allowed me to get my opinion on the real thing before heading to a fanedit.
