I had a gen 1 Glock 23 for a long time. I got it ported, tritium night sights, extended mag release, etc, and it was really nice for practice due to the reduced muzzle flip. But, as others mentioned, it was louder, and in low light there's really a lot of flame shooting up -- would definitely have blinded me in a low light situation. I also noticed a little reduction in bullet velocities.
So I bought another factory barrel for it thinking I would keep it around as my home defense weapon. But then with the factory (non-ported) barrel in place, the thing shot really high above the point of aim. That was because the new sights were set up for use with the ported barrel.
So in summary, just be aware of the limitations of the ported gun, and if you can accept those limitations, you would probably enjoy it.
