if you like old skools you will love the old skool pros. basically the old skool with a better insole, and suede to make it last a little longer. not one single complaint about those shoes, other than they maybe run a half size big (most vans pros do). if the old skool is your favorite shoe ever, it's no brainer.
i've never skated the TNT's, but I tried them on. they're sick, the only thing I didn't like is they don't have the ultra-cush insole, they have the ortholite one which is thinner at the heel and non-removable. that's the only reason I didn't buy them. the felt nice otherwise, i just need more heel support.
hope this helps!
