I have both tactical and thumb hole style stock's. I have the 535 ats tactical and as far as carrying it, its light and easy. Its real nice to set up and hold with comfort while waiting on a shot. Recoil is a problem when bench shooting but when it comes time to shoot a bird, the recoil is never noticed.
The thumb hole stock is on another gun and seems to be heavier, it does help with recoil but just doesn't have that feel you get from a pistol grip style stock.
I think you'll enjoy the tactical stle stock alot more, it just seems to have a better shouldering feel.
Just my .02
