The best bet would be for you to try to rent or borrow and shoot both. Determine which you like best, and make that your first purchase. I chose the PT-92, but that surely doesn't mean that a Glock isn't in my future. The hardest thing about selecting a Glock is to figure out which model best suits your situation(s).
I need a unit for C.C. Taurus doesn't make a model that interests me so I have to look elsewhere.
