McCarthy are pretty good, you should try to track down the compilation "That's All Very Well But..." which contains pretty much everything you'll need. I'm not as fond of their post-c86 stuff.
The Manics' debate was less about the respective merits of the two bands than what they symbolized: politicized indie band with 30 fans that can say whatever they want because they won't be heard vs. non-politicized million-selling band that can say whatever they want because no one cares what they think. Also one could argue that Guns N'Roses were political in the same way that Madonna is political: people pay attention to them, they mess with people's minds, they're cultural/sexual/social signifiers in a way that McCarthy is not.
