The higher rated winch draws less amps meaning your vehicles charging system has to work less to keep up with the winch. If you are running a single battery a winch will drain your battery down and put the load on your alternator . best information I can find is that the 392 has a 220 amp alternator #68417026AA with a hefty price tag of $632. I know winches have a duty cycle also but I couldn’t find accurate information on that but like a welder a winch will have an on/off cycle.
just for example, winch under load on for 35 seconds then off for 5 minutes. This allows the battery to recharge and the electric motor to cool. A higher rated winch using less amps will have a bit longer duty cycle. This is also the reason that heavy duty pickups have a dual alternator dual battery option with the snowplow prep package, like what was included in my 2020 F350. A long day of plowing snow will kill a truck with only one alternator and one battery. Living in Maine my entire life I have seen that play out several times.
Most of this is unimportant in situations like pulling yourself a foot to get off a rock but if you have a long distance to cover in a mud hole or snow you charging system is in for a rude awakening. Also take into consideration power loss for each layer of line on the drum.

With nearly identical dimensions (the 12s a bit shorter), only 5lbs difference and with a $223.52 msrp difference the reasoning behind Jeeps decision to go with a 8k winch will probably remain a mystery like so many of their other decisions. (red seats only

I still say buy what you want, rocks and ledge are different than mud and snow, weekend explorers are different than hard core off-roaders so it’s like my grandfather always use to say “not my circus, not my monkeys.”
as for 9mm or 45 acp and being out in nature, neither. 454 casull, mostly because if you shoot a bear with a 9 or 45 it’s going to shove that handgun where the sun doesn’t shine then use the rest of you as a chew toy. im not saying 454 will drop a bear in its tracks instantly but the odds of survival go up dramatically. Also you can shoot 45 colt for target practice with less recoil.
