I never heard of Jackson T-32. After checking it out, it really looks like a nice stat. As far as features go, I think it wins out. Depending on your schedule, you really could stand to save a substantial amount (hundreds annually) by going with a programmable stat. The obvious times to take advantage is when no one is at home, you can increase the temperature when away and program it to drop just before you get home.
If you don't want to program and are not using a heat pump system or have a 2 stage compressor and prefer simplicity, the 1F86-344 is the way to go.
