What exactly is "indie"? The term seems to be used for any band that uses guitars, bass & drums and isn't obviously pop or metal.
There are those dreary bands who sound like Coldplay impersonators (Athlete, Snow Patrol) but then there's loads of other stuff like Bloc Party, Editors, The Bravery, The Automatic, Hard-Fi, The Killers, The View, Kasabian and of course the popular Franz Ferdinand, Kaiser Chiefs and Arctic Monkeys. It's a pretty broad range of stuff.
But I take Sambo's point - I don't particularly like any of these bands (from what I've heard) so I'd hesitate to pick any of them out as better or worse than the others.
