Inbetweeners all day, even though I've been cursed to be the double of Will (and McLuvin from Superbad and, bizarrley, apparently the specky bloke off the IT Crowd :S)
Skins is what teenagers lives were like if it were up to them
The Inbetweeners is what teenagers lives are like in real life
Inbetweeners is funnier, Skins definitely had better storylines but who watches a comedy for the plot? Had skins ended after series 2, perhaps 3 it might have held on to some credibility but it didn't so my vote goes to the Inbetweeners
