CIS-E is more simple, sometimes that is what matters. I talked with Peter Tong on vortex many times, and he swears that CIS-E is the best and K-Basic is close behind. The real benefit that E has over Basic is the WOT switch and how it can also keep the fuel curve pretty level (even at idle, thanks frequency valve)
ME on the other hand, I prefer the basic at the moment. I have the whole -almost uncut- CIS-E (from a 1.8 rocco) and if I end up needing it, cool. Ive got a shim in the control needle on the dizzy and I will probably find me a vacuum dizzy IF I find the power not enough. For the moment I like it.
