Never have owned a dog-bone wrench and don't plan on recommending to anyone !!

Do agree for lube tech that it likely is best tool for the job since it's functional with drain plug being out in open; also, no hot oil on hands and quick to use. However, that issue could be eliminated altogether if manufacturers would standardize oil drain plugs in all vehicles !!
However, I'd never be without multiple vise-grips of various sizes and "noses" as they are just the cat's meow when you need them. Most of time vise-grips end up being portable VISE in the field to hold something so other proper wrench can do the job on the fastener. As other poster said, a vise-grips can act like 2nd set of hands.
As for Cresent wrench, it's probably the MOST universal and functional tool anyone can have, and should have! EXAMPLE: was at Joplin tornado victim's house and they had virtually no tools, not even a Cresent wrench to tighten wobbly legs on kitchen table!! Lucky I always have several tools in the car.
Channel-lock, Knipex, Robo-grip, or whatever slip-jaw tool you might have, they too are universal and functional tool EVERYONE should have. I've got one in every tool box and vehicle I own.
Compact sets of tools are also useful like the nested set of open-end wrenches that have little clasp that hold all the wrenches together. I've had Stanley set for 40 years and still my quick go-to set.
Lastly, blow-mold sets of 1/4 and 3/8 drive ratchet & sockets should be owned by everyone. For me, great memories of the sweet little green box SK set I used as a kid. Simply nothing better than those SK sets! - - Only improvement I can think of would be including breakover bar and thumb-drive ratchet in box as well !
