"BEST" is a real toughie to answer because it depends on what your intentions are.
KYBs are excellent for street use and, in fact, I installed a set on the 86 I once owned and loved them. However, they wouldn't be the BEST choice for a guy who likes to hang it our on a road course.
So, like so many other things, (which cam should I install, which tires, which cylinder heads, etc., etc) it depends.
Just my thoughts.
