I personally think they are the best. Good visibility without moving your head to the doors. I have a new set of the original door mirrors but will probably never put them on. You need to find someone who has them and try it.
I have to agree, they're awesome. There are zero blind spot's with the fender mirrors, you can see anything beside you without a head check.
They are annoying that they don't allow for a normal car wash though.
