I own the a 9mm subcompact and a 9mm tactical. I have also shot the Service model extensively. I like them all, but the tactical is my favorite. They all point and shoot about the same, except I can shoot lighter loads and still make minimum power in the tactical. I am in the ammo business, so I chronograph a lot of different loads and it may surprise you how much difference an inch can make sometimes.
ETA: The one drawback is that the heavier slide of the tactical may not lock back as easily if you are shooting a really light recoiling round and/or you gun gets a little gunky.
