Apparently, all the Tiger kits have an incorrectly shaped turret. So in that respect, it probably doesn't matter which kit you get. If you want to go to the trouble and expense, Tiger Model Designs sells correctly shaped resin turrets for the four turret mods. They sell for about $20 each and can be found at:
http://www.tigermodels.com/shop/tmd
(Warning, they seem to have either a slow server or a slow i-net connection.)
As far as kits in general go, if you want an easy, great kit, without an interior, Tamiya's can't be beat. If you want to do an interior, Academy is the way to go.
Good luck with whatever you decide.
