I'm originally from the Buffalo area and now live in the Rochester area. Pavers constantly move with the seasons, especially when the frost line is almost 5 ft deep!! You also get to put up with all of the "stuff" that wants to grow up in the cracks, no matter what you fill them with. I have lived with my 12X12 deck for about 25 years and it is nothing but a maintenance PITA!!! I wish I had done a 6" thick patio instead. My deck is only about 6" above the ground, but some critter or other is always burrowing under there.

Anything put on a PT deck has to be done yearly. Forget the semi-transparent stains because, after many years, it's not semi-transparent anymore. The latest thing that seems better than others is the stuff made by Behr and sold at Home Depot. I always doubted it until I tried it.
There are plenty of concrete contractors out there. As long as you can get the concrete to where you need it to go,
DON'T put up a deck!!!!!
Another bit of advice for a fellow Western New Yorker, get garage floor mats to keep the salt off your garage floor!
