If you like chunky necks, go with a Schecter. If you live or die with uber thin, then Ibanez, since with the exception of the AFJ957 hollowbody, and the ARZ Les Paul Copies, they all have the Wizard neck profile. Another thing to consider, is do you want an extended scale length (26.5" or longer). The higher string tension a longer scale length will give you keeps the 7th string tauter, and punchier sounding. Unfortunately (and I can confirm this from first hand experience, with a 26.5" scale Schecter Omen Extreme 7 I used to have), it also makes the higher strings sound a little screechy.
Me, I prefer the chunkier necked Schecters.
