Damn guy 11 Pairs of channel locks LMAO that alot!
I see no Channel Locks in that picture? Channel locks are 19th century technology with blue handles.
There are 7 pairs of Cobra's and I do end up using all of them quite a bit. Back when I owned channel locks I dreaded them and rarely used them. With the Cobra's I tend to look for a reason. Much more precise adjustment and the teeth really bite. The self locking box joint is what really sets them apart though, if you have not used them, try a pair once. Channel locks you have to squeeze and turn, Cobra's you just get it set on the piece and then put all of your force onto the "back" handle (the one connected to lower jaw).
This video probably shows it best.

The other 4 with the push button adjustment are in their own category. They are not "water pump pliers" like the channel locks and Cobra's. They are the Knipex Pliers Wrenchs. They are actually a replacement for a "Crescent Wrench" but better. The jaws are like an adjustable wrench, however the adjustment is obviously different. What sets them apart though is the self-locking design. Just like the Cobra's they lock onto what you are turning. You can apply more force with these than you can with an open end wrench and have less chance of rounding it off due to being able to apply more "squeeze" as well as rotational force. It still gets better though, the way they have the pivoting mechanism set up, it allows you to "ratchet" the piece apart. Its not finnicky line a "ratcheting" open end wrench, you can use these at any angle to ratchet. I use them all the time on basically every hydraulic or air line I run into. They work great for that application. They are very fast and precise.
