Two hip hop blogs you should be checking out

Tech N9ne is actually a vile human being who needs a bullet in his head, but okay. Common isn't fun though. The rest of your examples are A+ though. Playing video games all do does nothing to your brain. It'll strain you eyes if you look at it for too long, but the same thing happens if you read books all day or if you stare at any one thing all day. You're point is excess is bad, except excess doesn't correlate with Cam'ron or Wayne. They're both fun in a little ways. Wayne because he can absurd. Cam because he has an everyman quality to him when he isn't pretending to be a gangster. And they're both fun in edging close to self parody ways. I don't think Wayne is desparate for fan approval considering he sold 3 million on his last album. Cam has enough internet soldiers to revival even Joe Buddens, so I doubt he's hurting for more love.

Hip Hop is allowed to be fun. Lil Wayne and Cam'ron are fun.

I'd be hard pressed to argue that Lil Wayne doesn't rhyme effectively considering he's pretty much the same as the majority of rappers in that regard. He doesn't say anything particularly interesting most of the time nor is his diction anything to brag about. But despite the hate, he's with everyone else as far rhyming goes. It is definitely quantifiable how well someone can rhyme, but it isn't the the beginning and end of the discussion about how skilled someone is. I reject the notion that all art is completely subjective. Art may be wholly subjective in the sense that people "like what they like" but there is still a semblence of a rubric/structure that makes something grant. Obviously there are differences between the different arts but things like form and originality are definetly all encompassing.

You've never listened to Children of the Corn.

Skill in the craft is definable. There isn't a single definition and all the definition aren't quantifiable (ex. Humor), but you can define skill in the craft. Redman being one of the funnier rappers. Em being one the best technical rappers as far as multis, rhyme structure (internatl,end, slant, etc.) cadence, etc.

Obviously I wasn't being serious about Cam being the greatest rapper on off all time. But I doubt Reflect has ever listened to a Cam'ron song so his opinion isn't worth shit regardless.
