In reply to everyone:
The fit is the most important thing. If the shoes doesn't fit well, then the shoe is crap!
Onyx is Stealth Rubber. "Old" Stealth rubber was C4, "New" Stealth rubber is Onyx.
Lots of climbers do wear 5.10 even if they don't get them for free

Jerry Moffat did Master's Wall in a pair of Boreal Fire's not Jokers! They were the first pair of "sticky" rubber shoes in the UK. Cragrat has the correct spelling. I can't be arsed to find the e with an accent.
As for all the other stuff... what does it matter if your shoes are stickier than your mates? If your mate is a better climber, he will climb better than you full stop. I can burn (some) people off in a pair of trainers, assuming the problem is burly.
If you watch "Stone Monkey", then there's a bit of Johnny doing Technical Shitbag in trainers. It's all down to how good you are. Extra stickiness helps, but not much. In fact it helps so little, few people could probably tell the difference between two shoes, in different rubbers.
