I agree that the V850 makes for very nice 35mm scans unless you want to print huge. I used one for years and found it nicer in texture and color over Frontier/Noitsu scans.
Silverfast helps a lot with getting nice colors (although you pay for it not only with money but by using a horrible interface).
for B/W, it feels a bit soft, but they still hold up very nicely up to 20x25" prints.
camera scanning can give you higher resolution, but colors are tricky, grain structure can get mangled, and you don't get the benefit of ICE for color films.
