Which brand of guitar should i get?

I can't decide whether to get an ibanez, schecter, or ESP/LTD. I will be playing the guitar i get in drop B tuning. I play metalcore/deathcore and don't know which of these will sound best. i'm looking for a six string that sounds good in dropped tuning with good tones for lead too. Bands i play the most are Motionless in White, A Stained Glass Romance, Chelsea Grin, etc.
