I have a 48" cant hook and two peaveys, 30" for log deck work and 48".
I think a cant hook works better, grips better, on large single logs the size you mentioned.
I use the peaveys but again, they do not bite the log, they just hook it, and the larger the log the more I found the tip can slip, can pull back towards the hook. The peaveys are more versatile with multiple logs piled up. You can pry, push/pull endwise as well, and stick the tool upright in the ground vs laying them down when not using.
Mine are Log-rite, and I like the easy to spot bright blue color. Shows up well when using in the woodlot, and also in the trailer, so I know its going home as well.
Log-Rite's have a tough foam wrapped handle that I'm somewhat protective of when piling tools in to go. Mine has a few tiny chunks out of it, but it is very tough, dense, and a solid grip, barehanded or with gloves. I like their tool.
I have thought of welding a small bump stop at the base of the handle so the hook can not swing back to the handle and pinch my hand/fingers when I grab the handle low near the hook, as in carrying it horizontal.
