Unless you work a trade, I would go with Harbor Freight for everything except cordless tools. If you wear the Harbor Freight tool out replace it with something higher quality. For cordless, I don’t know. I have Dewalt and wonder about others. I mostly avoid cordless now.

For trades, see what your coworkers are using. Do you want them borrowing your batteries? (No) Do you want to borrow theirs? (Do you want them to dislike you?)
