To the comments about hydraulic (and I'll include PTO) winches, they are pretty typical as the vast majority of people aren't familiar with real ones. IMO a PS pump powered winch is a toy.
Proper control of a winch's operation is a safety issue and hydraulic and PTO winches offer the greatest control and thus safety. You can vary the speed as needed. As slow as needed all the way up to faster than most electric winches, especially under load.
The other major advantage of hydraulic and PTO is that they are, for all intents and purposes, 100% duty cycle. I don't know of any electric, no matter how well built, that matches that.
What this means is that there's seldom, if ever, any need to use vehicle tractive effort to assist the winch. Using vehicle assist is more often than not hard on the winch, the vehicle and definitely on the landscape.
As for being able to winch with an electric when your vehicle is not running, I don't see that as a particularly major argument. Mostly it's perhaps a big deal if you travel alone and, personally speaking, I'd never travel alone in a place I needed a winch unless I had a backup method of winching, like a hi-lift or hand winch.
As for hydraulic and PTO being more difficult to install, yes. But people upgrade axles, do engine conversions, gearbox conversions, and all sorts of other work like that, then they're going to complain that a hydraulic installation is too much work? I guess it depends on how much one values reliability.
These comments are relative to the theme of this site, traveling alone or in small groups, not things like competitive events or traveling in large groups for a couple of days off-roading.
