If I had 750-1000 dollars to spend on a suit, I'd probably go the OTR route as I'm a fairly standard size (6'2", 40 chest, 8 inch drop) and if you take out the extra expense of MTM, I could get one level up of suit (materials, brand as a quality proxy, etc) and get it tailored for the same price as a MTM suit of slightly lesser quality.
