i own them both, in general :
dellinger is punchier than the TAT, maybe because the TAT has neck through construction, so the sustain will a little bit 'over' when you play with heavy distortion.
TAT is heavier in weight than the dellinger ( comparing TAT Frozen Sky vs Dellinger OIL Mahogany).
for those who likes unfinish/ satin finish kind of feel neck : Dellinger is the one.
neck access for both is quite the same, neck's feel is almost the same, except for the finishing differences.
body comfort :
TAT has curved top body with no arm rest, but the angled body to neck construction makes it quite comfortable to play, almost feel like a 'normal' guitar with arm rest to me.
Dellinger feels like any other guitar with arm rest, nothing special.
the neck dimension :
both has compond radius fingerboard.
both has thicker maple neck than any RGs, but yet has fast- feeling , I've been a Wizard neck fan for so long that I can't even remember, but switching to caparison TAT and dellinger's neck is not a big problem for me.
sounds :
high output pickups, deliver aggresive modern kind of raw distortion and singing leads.
controls :
push push tone know as coil switching makes the humbucker to coil tap, but makes no mistakes, you won't have sparkle single coil
strat sound even in coil tap mode, because this is caparison, they meant to be 'heavy'.
hope that helps.
