funny you say that I have a plug in electric impact wrench - and it’s great for the main thing I use it for. Tire removals.
Reason I don’t use it much more - space it’s fairly large
Of the cordless devices - and I’m going to assume here you use 1/2 inch drive sockets for your impact needs - I like the new Dewalt Cordless product. They updated them about 2 years ago and they work really well. I think it might be the current strongest impact wrench on the market today. They make a smaller more compact one now also and that might be the one I would pick. Don’t so much need the larger full torque model and the smaller one might get into more places.
Milwaukee makes one too - I’d consider it also and probably before I’d consider a makita.
For the drill - either is a good piece of Kit. I bought into Dewalt and I like their made in America attempts.
So I’d get a dewalt drill with charger and battery or 2. I’d consider a kit with a impact driver but you didn’t mention wanting one. I’ll say this - I have the upper spec Dewalt one with the 3 speeds and I love it. I also throw a 1/4 square or 3/8 square adapter on it and use it to run in bolts all the time.
Then I would get the impact wrench as a bare tool to save money and I’d even consider a CPO purchased reconditioned one.
