That's like saying "what are the best hubcaps for a car", there are many types that are better for different uses. My wife just got a Kona Smoke with "full coverage" fenders, they basically encase the tire preventing it from getting anything on you.
If you want a motocross look, look up "THE" fenders.
If you want very good coverage there are "planetbike freddy's" but they look kinda like cruiser fenders.
I had the seatpost fenders with the adjustable knobs, but if i bumped it with my foot or anything it would snap right off (broke 2 and gave up).
Then i went to the "zefal cruzer" fender, it looked kinda cruisery so it looked funny when i was on backwoods trails but it worked pretty well. I gave up on those because i couldn't get them to not interfere with my rear v-brake. they had a metal frame so they were very sturdy but when i upgraded to discs i needed those holes back.
I also had a frame-mounted rear rack, worked as a mediocre fender by itself, worked pretty well with a newspaper attached hanging off the back, but also, uses the holes that i needed for my BB7s.
now i have no fender in the rear.
I only had one front fender, a standard steerer tube one, but took a large jump and it broke off, i'm not sure how as it was very fast, i'm guessing my tire hit it somehow.
now i have the downtube mounted "mud guard" not as good of a fender but stays out of the way.
