Even if you decide to go with the new furnace, if you haven't had a proper sizing calculation done then you may be WAAAY sorry you got the new one. You cannot simply drop a new furnace in to replace the old one like you're buying a new fridge. If you bought the same BTU furnace then that is definitely a big mistake since it will be rated as BTUs input, not output. With a 95% furnace vs your old 60% furnace you have a 1.5 times too big furnace....and no, that is definitely NOT a good thing. It'll be far less comfortable (excessive cycling and temp ups and downs), more expensive to run, and will wear out faster (excessive cycling). Make sure the furnace is sized using the "Manual J Load Calculation". If your contractor doesn't do that tell him to take a hike.
As far as a properly installed furnace is concerned, it is unlikely you'll notice any difference unless perhaps you get a two-stage furnace, or variable speed fan or some such, though those are less reliable than the ordinary ones.
