We use tools daily at work. Ergonomics, ease of use and reliability are key, in no particular order. For these reasons I've chosen these brands...
Ratchets...
www.armstrongtools.com For some odd reason the website won't open. I prefer the smooth handle as opposed to the square handle. Repetetive motion goes over better with the smoother handles, IMHO. Personally I haven't had a problem with handling them with greasy hands. We use them for steel construction, electrical connections and everything inbetween. I can only remember breaking one with abuse. the phrase 'drive it like you stole it,' comes to mind.
Screwdrivers, nut drivers, diagonal cutters, lineman pliers, electrical multitools...
www.kleintools.com The screwdrivers and nut drivers are so comfy. Nut drivers are hollow, so a long screw/bolt won't bottom out prior to reaching the nut (unlike craftsman). They're tools are high quality and very reliable. The blades are strong and the grips are comfortable.
'Quicky's' Or reversible ratcheting combo wrench, we use craftsman. These are the best things on earth! Lighter and easier to use than a 1/2" drive ratchet makes unbolting things much 'quicker' They have the 5 degree tilted head and adjustable head. The one's that are flat are pretty useless, IMHO. Craftsman also have those super cool sockets that fit in the ratcheting part for those especially awkward moments. I believe SK makes them as well.
www.skhandtool.com SK makes VERY nice tools.
Crescent brand pliers are my favorite. The famous blue handles. I'm sorry but the craftsman pliers are crap. Leverage, ergonomics, quality are superior with Crescent brand.
Off the top of my head, all other tools in the craftsman flavor are fine.
