I don't see anybody disputing the fact he is a talented musician.

Songwriting however is a totally different kettle of fish. And that in my opinion is where he lacks.

Fair enough...

Dave is a excellent drummer, decent guitar player, good voice, but choses to make radio rock.

Not really sure bout that one. I heard a live performance of them on TV, and his singing was very sub-par.

I think he a decent vocalist he's not Kurt, buthe gets the job done.

Dave has a much stronger voice than Kurt, I just don't think it's distinct enough or particularly interesting. Vocals aside, his music just sucks.

Kurt has a stronger voice than Dave. Just listen to Territorial Pissings.

Thats your idea of a strong voice?

He sounds like he's coughing up a lung to me

Yeah that's because he's singing so hard.

If you sound like that because you're "singing hard" than you're not a very strong vocalist. You really need to stop trying to argue points you know nothing about. Kurt Cobain from a technical stand point was a very very inferior vocalist to Dave Grohl.
