Probably "leave it on 24/7".I have a related question... Which of the three options listed helps prolong the life of the power supply the most?
Sleep sends standby power to the RAM and NIC (and power switch). The main power supply circuits are off, and will surge when you power up.Wouldn't letting it sleep alleviate that stress?

I recently measured mine with a "Watts up?" device. The computer itself measures 7.8 watts sleeping. The I measured at the input to the UPS = 30 watts. Connected to the UPS is a cable modem, LinkSys router and the 23" ACD in sleep mode.
Idle run mode measured 172 watts for the computer and 228 watts measured at the input to the UPS. Idle running power factor measured around .9, not too shabby for a computer!
Mac Pro startup or wake-up from sleep draws around 10-11 amps very very briefly at a low enough power factor that the startup peak watts measured 269 from startup and 222 waking from sleep.
IPS panel burn-in
Thought that was only really a thing with plasma displays and modern LED-LCDs are very hard to burn in
It can still happen. Here's a posting from Apple about the issue dated 2016:
Right, ok. By the sound of it, it's only temporary though. Wasn't always that way with the plasma burn-ins.
I have personally seen it happen to the point where nothing would fix it.
What do you do with your MacPro before you go to sleep?
I read to it!
