I tend to prefer certain brands for certain types of tools (and in some cases do NOT like some brands). I'm just a DIYer though, so I don't have experience with everything, but I'll summarize my preferences below.
Ratchets - Snap On, I really like their ratchets. I haven't tried the high tooth Gearwrench ratchets, but heard very good things and would try without hesitation if I needed more ratchets. Nepros is another interesting brand, hard to get, beautiful quality (toolbox jewelry), not cheap and completely unnecessary considering what we readily have access to, but I have one ratchet and one adjustable wrench and love them! I tried a Wera and didn't care for it much. I think it was too short (but not short enough to replace my short craftsman ratchet), the odd handle and plastic bits didn't sit well with me. For some applications that swiveling head can be useful, but for auto work, this didn't appeal to me.
Sockets - Williams USA made if that floats your boat, or their Taiwan line. Easy to discern what's what from the part numbers. Wright Tool is also good. I've not been pleased with SK (finish is a little rough, chrome plating flakes off). Koken (Japan) makes some really nice sockets for a reasonable (but not cheap) price. I prefer 6 sided sockets for fasteners under 13mm. Koken makes an interesting lobed profile socket to avoid rounding over fasteners, but it certainly makes it interesting when you're not sure whether the fastener is SAE or metric because that socket will always have a little more play than a standard straight walled socket (so many will not like this).
Impact socket sets - Sunex or Gray Pneumatic (both Taiwan I think)
Socket bits - After breaking a few torx, I ponied up for Snap On (gold colored bits) and they have been really great. I would spend money on good torx if you encounter them frequently. VIM Tools (Taiwan) offers some good quality socket bit sets.
Screwdrivers - Snap On, Wiha (their heavy duty version). I also have some older Craftsman Professionals that are very good, no idea if they still are? There is a lot of personal preference in the handle design and ergonomics. As an example, I can't stand my Wera's. The handle design isn't all that appealing and the tips aren't durable either. Vessel (Japan) also has some nice screwdrivers.
Ratcheting screwdriver - I like my snap on, but mostly because of the handle shape.
Pliers and Cutters - Knipex, Channellock. Durability of Knipex is outstanding and some of their pliers are truly unique. Channellock is high quality USA made stuff. Grip On makes some nice locking pliers (I think they make them for Snap On). For slip joint pliers, I have a set of Snap On's that have a cross hatch pattern in the jaws that are terrific!
Ratcheting wrenches - Look for something with a low swing angle. I have Snap On's, but they are stupid expensive and I know you get Proto, SK's or other good quality at a better price. The Gearwrench pieces I have are okay, but don't have a low swing angle.
Picks and hook sets - I got some from PB Swiss that haven't broken on me, even the miniature set. I would get them again if they were lost.
Pry bars - Craftsman Professional when it's on sale. They will take a beating and the handles are nicer than the non-Pros for a little more money. But the non-Pros are also good.
Torque Wrenches - I have a precision instruments split beam with a flex head for the larger bolts (which I love) and an all metal SK clicker for the 3/8" stuff and a Snap On for the 1/4" stuff. All are great. The plastic locking rings on many of the craftsman's wear out, I gave mine away after 20 years of faithful service. Harbor Freight actually has cheap all metal clicker style torque wrenches and they are accurate and consistent! At $10-12 they are a bargain and a fraction of the cost of the others. Usually this isn't a place you want to economize, but I know several people that have bought these and I checked every one.
That's all I can think of off the top of my head. If there are specific types of tools you're interested in, post that and I can add more detail.
