The click doesn't bother me. I suppose it is an advantage when it comes to difficult sections, that it holds the tempo steady and stops those really technical bits from becoming impossible, if the whole song was to go at a quicker than normal tempo.
I wouldn't say it's cheating though. The guys still have to play those bits at album tempo and get them as good as they can. I'd say some of those sections would be close to their own technical limits of ability (and way beyond mine), so to attempt to do them any quicker would be suicide.
