mine is far from perfect. he's always making a mess and pointing. (it's rude to point)
I'm happy with my 7+. Most people can't even get all of that in their mouth. And I've never had a complaint. Only invitations to come back for more. As far as other penises go. I like a large one. It gets me off trying to deep throat a large one. But that's me and probably a few others. Not for most.
Proportioned, anything above 6" is fine as I'm a petite build, love cut cocks with shaven pubes or else neatly presented. In nice undies though they will be pulled off very quickly... Would love a nice thick 7"er...
But what a man does with his cock is most important. A 9" cock might sound impressive but a 6" could be far better...
I'm happy with what I have.. The key is learning to use it the best way possible don't try shit that won't get your woman off.
