I live in the NYC area and have a large stamped concrete patio which I had done about 7 years ago. It looks good and overall, I'm happy with it. Like you, I was considering pavers as the alternative. I haven't had pavers, so I can't directly compare them. However, what attracted me to stamped concrete, besides the look, was not having to worry about weeds or potential future uneveness if some of the pavers were to move in realtion to others.
One thing I did not realize, was that stamped concrete needs to be sealed about every 2 years to keep it looking good. Otherwise, weather will gradually deteriorate the surface, so that it looks worn and beaten up. And if that happens, it can't be repaired. The sealer also gives it a shiney look, which I think looks good. You can also seal pavers to give them a similar look, however I don't believe it's really necessary to keep the std finish looking good. So, I think the maintenance issue between the two may be a wash.
Also, as with any concrete, stamped concrete is prone to cracking. If it's done correctly, this can be minimized, but it can still happen. With pavers, that problem is eliminated.
