Both....they both did some great stuff IMO....the rivalry was all media bullsh*t. I think Blur were more creative musically, but then the gallaghers wrote some great sing a long anthems....
Oasis I remember going to our price and seeing blur and oasis on the shelves and I chose oasis never looked back!
Liam a noël came to my works leaving drinks in the pub round the back of work. Ok they used to drink there.
