IMHO both have their distinctive uses. I like VG-10 for it's nice clean feal, it's reasonably easy to sharpen considering it's edge holding abilities, I like it for my indoor knives.
CPM-440v is a great outdoors steel. Holds an edge like nobodies business and cuts through the most reluctant of materials like they were butter. A good example, sometimes a highly polished VG-10 blade will sometimes just run over the surface of a slick / tough material, but CPM-440v just digs in and starts cutting.
I will admit that CPM-440v can be a bit tough to sharpen, I had a knife arrive reciently that was BG-42 (that to my untutored eye, feals very much like 440v), but it wasn't to the normal sharpness I have become acustomed to. It took a lot of time and effort to get a fine edge on it, but despite a lot of medium / heavy cutting since shows very little sign of fading.
