Johnny Marr is one of my favourites for sure, incredibly melodic, intricate, imaginative talent. I've always been a fan of The Smiths since way back. I'm a fan of Morrissey's lyrics too, from the hilariously funny stuff to the ' Oh woe betide me why have you cursed me so!' stuff
Boz Boorer the guitarist on Morrissey's - 'Vauxhall and I' did some really nice work there too.
I'd also add I think Andy Rourke is a criminally underrated bassist.
