I've had both, and without a doubt, an absorption (propane) type is more efficient. It's slow to get going, but once it does, it sips propane and can run for weeks. Ideal for boondocking.
When you put heat in to get cold out I would not say it’s “more efficient” but it does use less electric power.
When I say efficient, I'm talking about taking enough energy to run the fridge while boondocking. It's easy to take enough propane to run the fridge for several weeks. But how are you going to supply 120VAC for the same period of time?
Might do it with solar. That's a LOT of solar panels and batteries, which require mostly clear days to replenish, OR, a LOT of gasoline for the generator. I have 1KW a solar setup on my home, and a 1000AH AGM battery bank. Here's how two of my fridges compared:
Refrigerator in garage: Not running but on: 0 Watts. Compressor running: 114-140 Watts. Total per day: 1.15 KW, 47.92 Watts per hour average.
Refrigerator in house: Compressor running: 146 Watts. Defrost: 572 Watts. Total per day 2.15 KW, 89.58 Watts per hour average.
During a major power outage (hurricane), neither of my home fridges will be powered. I'll put items in my 40 quart Engel fridge instead.
If you're at a campground, with unlimited AC power, there's no comparison, but that's not boondocking. ;)
