I have almost every brand under the sun but here are my favorites:
Sockets: Gray Pneumatic is my #1, Carlyle is #2, then Sunex, Craftsman, some Harbor Freight
Wrenches: I am almost exclusively old style Craftsman but I do have some specialty Proto, Snap-on, Mac, and Matco
Ratchet wrenches: Gearwrench and a handful of Icon. Nothing beats Gearwrench here.
Ratchets: Gearwrench is my go-to, then Duralast and Evercraft cheapo's. I have 100+ ratchets including some high dollar ones... sometimes the cheap ones just feel better.
Screwdrivers: Milwaukee is my current favorite, Craftsman for nut drivers
Picks: Snap-on... they make the best picks out there.
Normal pliers: Channellock brand but Proto is a close #2
Slip joint: Knipex, nothing is better
Crescent wrenches: Old Craftsman & Proto
Needle nose pliers: Snap-on & old Klein (not new Klein) are my top #1, Milwaukee is a distant second
Hammers: Snap-on, Estwing, Matco, Lixie are my favorites
Vise grips: Old Peterson vise grip or Irwin are both good, and oddly so are Hart and Duralast.
Some brands are really good in some areas and not others. Gearwrench makes what I think are the best ratchets out there but their sockets suck donkey balls. Carlyle sockets are so good but I'll pass on a lot of their other tools... Matco is almost all rebranded & price doubled other brands, Mac has been crap for a while but used to be pretty good. Milwaukee is stupid expensive for what they are and not top quality either. I'm kind of a Snap-on snob but it has to be new stuff - I don't really care for most of their old tools (90's and older.) There are some really common ones that you can pick up cheap too - I have never had a bad Proto tool and you can pick them up CHEAP.
Just my 2 cents, I have no patience for shitty hand tools but I'm not willing to spend a premium for Snap-on so I shoot for the next level down if I'm buying new and also pick up a lot of used stuff from pawn shops.
