Two stage is great if you can afford it and you have a thermostat that can control it properly. Think of it as having two settings for your furnace, warm and hot.

If the house cools off a little, it will heat it back up with stage 1 (warm).

If you come home from work and turn it up from 65 to 68, it will kick on stage 2 to hear your house up quickly.

The advantage is stage 1 keeps the temperature more consistent so you don't feel hot/cold/hot/cold as the furnace kicks on and off.
