If you boondock alot the 12 volt is the hands down winner
As I said when I was "in the dark" overnight the Residental fridge got the big inverter with the big batteries... The little 12 volt only chest freezer that hits -4ºF making it a "Deep freeze" got a 12 amp hour LiFePO4 and a 300 watt msw to feed it's brick as I could not find the 12 v cord (I think I know what happened to it)
3 amps at 12 volt beats 10 or 20 or 30 (For 120 volt appliances take wattage and divide by 10 to estimate 12 volt amp draw... that covers conversion/inverter loss.. Works well up to around 100 amps/1000 watts.. Tested myself).
I say again go with the 12
