IMO, on performance and usability alone -
Combo Wrenches - wright grip
Ratchets - snap on dual 80, especially on designs like 18" flex head. SK round heads just -feel- good for me, I really like those.
Extensions - koken with the FAT knurling
Wobble extensions - snap on
Sockets (outright griping power) - Snap on FDX (Too many good sockets to really split hairs beyond that)
Impact sockets (outright gripping power) - Matco non-slip.
Locking pliers - Malco (snap on rebrands now)
Pliers - knipex/snap on/channel lock/tsunda/engineer/wilde/etc. Lots of good ones.
Electric - M12, too cheap for m18 so I use air.
IMO koken wins holding-sockets, much better than magnetic. Wera? has holding function bit sockets, so they're amazing in that category, but my go-to are half cut VIM sockets. Liking my astro pneumatic stubby and universal sockets. My new stubby impact from them is awesome. SP air for air-ratchets, they have impact mechanisms and are strong. Norseman vortex point just chew through stuff, but I usually reserve those only when needed. Nupla and trust-cook deadblows. I like the nupla handle more, I'm thinking the TC will last longer. Wilde pry bars with the plastic hard handles, I like williams for hard handle drivers as I dislike almost all manner of comfort/soft grips.
Screwdrivers are a handle preference thing. It's almost all preference for a lot of things. Matco makes a great ratchet, thinner than snap-on. But without warranty service is it worth it? Buy a similar gear wrench with a crappier mechanism for the flex head? Buy a matco and swap out GW guts when required at your own cost? What if the situation is reversed, you have matco, but no snap on driver? Proto, snap on, and wright all make very nice wrenches. Well wright don't make long pattern, so if that's what ya want they lose that category. Short answer - it's complicated. Lots of great tools out there. I got snap on boxes stuffed with every brand around and they're all valuable members of the team that get the job done. Most of my stuff isn't snap on, despite what people assume by my storage.
