The old manual Honeywell dial type. And you'll have to pry it from my cold, dead hands before I would 'upgrade' to a programmable.
In the same way that I like a regular, old-fashioned dial type volume control/knob on my audio equipment. I don't want to click a button X times to get to some point. Just grab the dial and go.
As I said in the other thread, I turn it down whenever I leave the house. Just like locking the doors, I flip the dial down - you can feel the 'stop' so I can do it w/o even looking, and it takes a millisecond or two.
Turn it up when I get home, easy to see where I want it, just one quick twist. Done.
A programmable will never anticipate when I come and go. Or when I decide to go to bed at 10PM or 2AM. And since we keep it cool during the day, I also turn it up when I take a shower, to get the steam circulated and keep me more comfortable when I get out. No clear schedule for that either, since I need it on just before I shower to have it still on when I get out.
And it won't anticipate that I'm working on something and am getting overheated at 64F, or the next day I'm reading, and feel chilled at 64F.
Programmables are fine if you are on a regular schedule, or want remote control. I find it easier to just grab that dial to suit my needs. I 'override' any set format more often than I would let it ride. I find manual simpler for me. And I'd bet I'm saving money, as my manual control keeps it only as warm as I feel I need.
I'm the one 'other' vote, as 'Manual (no program, just a setpoint)' didn't seem to match. I don't use a 'setpoint', I adapt to my needs.
