I don't have that much experience but I like half hollow/quarter hollow the best. For size I don't really have a preference, I like my 3/8 le grelot and for me it shaves just as well as my 8/8 gryphon. Only perks to larger razor is holding more lather, my gryphon I just rinse lather off when I am done with that hand. Will say though I like my blades to be on the lighter side, my gryphon is not really that heavy and fits my hand perfectly. My other razors are 5/8-7/8 and I don't really prefer any of them over the others. Although if I was going to stick to 1 razor for res of my life I would go with a 5/8 maybe a bit smaller half hollow blade, square point.
