Another real contractor here. I'll add that the knockoff batteries from Amz or eBay have worked well for me. I don't think the 6ah ones are really 6ah, but they last long enough and cost less than half of the genuine batteries. I've had Makita for the 18v lithium since it came out in like 2006, and have been very happy with it. I've worn out a few drills, impacts, and circ saws, but the life is more than acceptable. If you can swing the cost difference, the brushless versions are way better.
I have Milwaukee 12V tools and they are also good. The Fuel ones (brushless, burlier) are significantly better than the regular ones. The Fuel impact driver with the larger battery is enough to screw off a small deck with 3" screws.
I have a Powermatic table saw that is a real pleasure, and far, far better than the "contractor" saws I've used. But $4k and a huge stationary tool are prob not for everyone.
Festool makes great tools, and the track saw is superior to the Makita (I have a TS55, one of my carpenters has the Mak), but I can't justify the price differential for most of them.
For oscillating multitools, Fein is still the nicest. Everyone should own one.
When torx screws came out the industry should have been prohibited from making any other head types. Do yourself a favor and splurge for some GRKs.
For occasional homeowner use, I suspect the Ryobi would be adequate, and you can spend the savings on clamps.
