Over the last few years I've been using Milwaukee M18 tools, mainly just the 1/4" impact driver, drill, angle drill, etc. I've reluctantly stayed away from the brushless because mine were good enough and I thought the first gen would get improved pretty quickly. Anyway, second gen M12 has been out a while and Milwaukee released a few tools that caused me to jump and upgrade to most of the M12. Specifically the M12 3/8 Impact. This isn't a powerhouse that will break giant fasteners but rather a small compact tool that is useful for the majority of the fasteners I am likely to remove. In the process I switched to the M12 1/4" driver, 1/4 ratchet, and 3/8 ratchet. 18v and 20v are easily more powerful tools but 12v far more convenient.
For comparison, M12 1/4" driver vs. M12 3/8 Impact
Also, if you're waiting to buy a electric ratchet, don't. Your elbows will thank you. The gen 2 Milwaukee ratchets are out but in my opinion aren't an improvement over gen 1. Gen 1 is smaller and puts out less torque (you don't need more torque, it's a ratchet, just pull on the tool if you need more torque).
When I worked at the power plant. We started off with DeWalts. The batteries would not last a year before replacing them. The tools would last about 18 months before hitting the scrape pile. Management had a love affair with DeWalts. Took me 6 years to get them to change to something else. Ended up with Milwaukee's. They're still using the Milwaukee's. Working at Home Depot part time. The most returned cordless tools is DeWalt. Hardly see a Rigid or Milwaukee returned.
rigging company was over this afternoon planning the move.
