That is a touchy very personal subject. Mostly involving what the person is most often engaged in. I don't do "mechanic" work, at all, except for myself. But I do electrical work for just about anyone that asks. Just I won't "jerry rig" anything, I do it right or I don't do it at all. With that in mind, I do use combination wrenches regularly. And for generic sheet metal screws, prefer the hex head and phillips combination head when I can find a particular size.
For my end wrenches, combination with open end and box end being my preference, I use a number of racks like pegboard pegs but in a group. I don't know the brand but they are 8 or 10 pegs to a group. Each peg per size. . . 6 and 12 point wrenches are not differentiated, but on occasion when I need 12 point specifically, they are easy enough to pick out. Imperial and metric are on seperate racks, side by side. There are several "sets", mostly odd sizes picked up over the years. And a couple of true sets that were acquired, some good, name brand, some cheap, a la Harbor Freight.
There are many wrenches, some with odd sizes, that are specific to some machine. And a set of very large open end with an odd angle on the head that do well on woodworking machines. Those stay with the machune. Then there are "ignition" sizes. The small and oddly shaped sizes. Those are in a plastic covered bin in a drawer of the tool box. And lastly, there are the wrenches for tiny sizes specific to my models. The 5/32 and under sizes. Those are in a (homemade) stand on the back of the bench.
Sockets mostly stay in their original set boxes. From 1/4 drive, 3/8, 1/2, and 3/4. Then there are the "nut drivers", spin tights(?). The "normal" sizes (3/8-3/4) reside in a tool box. The small ones that I made are on my model building bench. Again, homemade racks. And metric and imperial seperate but close. There are many spin tights and wrenches from my professional days that are no longer used much now that I'm retired. Those that are specific to a piece of equipment are kept in "deep" storage. Odd stuff for old model recorders and the like. I never throw anything away. Ya never know. . .
