I have a 9" Xcellite set that is my favorite day job set. Full length cutters, good serrations on the jaws for grabbing thin material.
Next favorite is a 7" Cresent (1950-7). Similar to the Xcellite in jaw configuration, the handles are comfortable. I have had these since I was a kid, either got them from my uncle or grandfather, they are my goto set most of the time.
I've got a few more, including a cousin of yours, the 369CR (crimper), my only complaint with these is the jaw gap is too wide for most of my uses (pulling on sheet metal, no grip at all) bought these for the day job as well to have the convience of a crimper in it, but since they can't grip anything they stay at home. Compared to all my other linesmans (I have a few) the handle tops are mostly rounded and not as pleasant to bear down on. If they had the flat top handles like the 909 or older water pump pliers I think these would get used more often.
My Grandfathers favorite pair where a 70's era 8" Mastercraft (Canadian Tire). It was his goto, and it is also a reasonable comfortable design, I inherited those, don't use them near as much as my Grandfather did, I find the handles just a tad too far apart. But those things have cut through every imaginable kind of wire to be found on a farm and fence, probably been hammered on, hammered with, pried, poked, proded, pulled nails, cut nails, etc.
So, in short, its the comfort of the handle IN USE that is the deciding factor in what linesman you end up using, not the size.
Throw that packaging away already! Its a tool, not a trophy. =-)
