I'm also replacing my furnace/AC in upstate NY.
In my old home (in another state) I had a perfectly sized two stage furnace with variable speed fan. In the winter, it ran often and long - All the air in motion was warm.
We also had a two stage A/C and it was very nice. It was able to keep the house temp "even" whether it was 80 or 95F outside.
We're going to upgrade the existing furnace with a version of what we had and liked.
Your note was about the AC. However, in this climate, I'd focus on the furnace rather than on the AC unit. That's where most of my energy bill is spent.
I don't know anything about the equipment you've mentioned, but, for comfort, you can't beat a properly sized, multistage, variable speed furnace. Perhaps you've already considered it. However, if you haven't, you should.
