If you had to choose between the two, which would it be?
Obviously neither are great, but the choice is between Beatles rip-off or Radiohead rip-off. Oasis are infinitely cooler, usually I’d say they’re easily the better band. But if you ignore whether they’re cool or not (you might argue neither are) and just compare their best works (songs from both of their first two albums and maybe bits of Be Here Now, X&Y and Viva La Vida) and ignore their bad stuff, it’s a bit less clear which one is better.
I think I’d rather have the option of listening to The Scientist over Wonderful, tbh.
