Ergonomics matters. I bought an 18V Milwaukee cordless set, drill and impact driver, relatively cheap and reliable, but the low angle of the chuck combined with how the battery projects too far forward is bugging the crap out of me on the impact driver. Wish I'd gone back to Makita.
Some corded tools are still made in the USA, all cordless are made or at least assembled elsewhere. Batteries themselves on my Milwaukee tools were started in Korea and finished in China.
Finish nailer (15 gauge) from Harbor Freight has held up over the last year, doesn't jam or stick any more often than others I've used. Not sure I'd gamble more than fifty or a hundred on an HF air tool. At HF in general, the few moving parts the better, don't rely on anything that needs precision, and expect pockets of slag in the castings.
