I have always found it interesting that Schecter tends to market towards rock and metal, yet their necks generally seem to be really thick. You'd think they'd have a few more guitars with thinner necks to cater for the shredders. I own a Loomis 7-string, and whilst I found it the best out of the Schecters that were available at the store (Blackjack, Hellraiser, Omen, Damien), it would definitely feel ten times better with a thinner neck. That said, I reckon it rips the shit out of Ibanez 7-strings in the same pricerange.
In terms of 6-strings, LTDs to me feel like they have an edge over Schecters. The build quality is somewhat similar, but I prefer the necks and overall aesthetics of LTDs. For the most part yeah, it's a personal preference thing, though if you intend to do lots of fast soloing, you might find LTDs will suit you best in the long run.
