both will be a big step up in terms of quality, hardware, componeents and build. Necks are generally very nice even on cheaper ibanez guitars. Squiers are hit and miss, good value if you get a good one but there are some real planks out there as well. floyd rose trems are generally pretty stable but u have to learn how to balance them, worth the effort though. Does the LTD have active ESP pickups? Is that the sound you are going for? (metal/shred, high gain). If so then go for the esp. If not, I'd take the ibanez. I'm sure you'd be delighted with either.
