I don't do much with appliances as I don't have a truck. I may snip wires off some of them, but much of the wire I get is not worth stripping. I get a lot of that small soft 30% type wire- I get about the same and sometimes more by leaving it insulated. I do like to strip ROMEX and some types of THNN/THWN wire. The stripper I have is manual and made by TNT Tooling- it is ok, but not as good as what I was expecting from looking at the Youtube videos (like MooseScrapper's) before I bought it. For instance, on some of the THNN wire there is a clear plastic coating of insulation on top of the other insulation. Sometimes that plastic is quite difficult to remove and then you have to strip the wire again to remove the other layer of insulation. Sometimes it is so hard to remove that I stop trying and sell it as insulated.
