You shouldnt be using an impact
driver on automotive nuts and bolts, so the 2nd two are out.
I have the M12 power ratchet and I think it's well worth it. Recently took the cams out of a truck at the pick n pull and it was a great time saver. Also just did a valve cover gasket. Really glad to have this tool.
I researched these and there's a harbor freight version, but I dont think it's worth it. If I wanted a knockoff I'd buy this. At $70 it's $20 less than it was a few months ago when I was looking. If it had been this cheap then I probably would've bought it instead of the Milwaukee.

When I bought mine Home Depot had a deal going where you if you bought the M12 battery starter kit for $100(a 1.5ah and 3.0ah plus charger) you got to choose a "free" tool as well. So I got two batteries and an oscillating tool for $100. Then I bought the M12 ratchet tool only on Amazon for $80. Not a bad deal and I may want some other M12 tools later.
If I had bought the Amazon knockoff I wouldn't be able to expand it.
