I'd say I rate them equally... Here's why.
-VOTC Han... The sculpt is fantastic and spot-on, save for the hovering holster. I'm a little miffed at a non-removable vest in this day and age, that knocks the figure down a peg slightly to me. He is near perfect though... I have some I like a bit better I think, but he's right up there with the best in the line really.
-VTSC Han Endor... The sculpt is again fantastic in my view, with or without the jacket. However, he has two flaws. The same hovering holster VOTC Han has obviously, and also he has the noticeable gap and some slight sculpt inferiority without his vest on... However, with this Han you get the spiffiest softgoods accessory in history, complete with working pockets even. The blaster also got a paint upgrade despite its inaccurate sculpt.
To me they're equal... Take the jacket from VTSC Han though and I'd probably lean more to VOTC Han. The jacket made the figure (and made the price a fair bit easier to choke down).
