Last year, having come back to electric onroad cars after over a decade of void, I got myself a Futaba 4PKSR from a friend's recommendation.

Now, one year later, with the 4PX is coming, having just sold my 4PKSR tranny, at this conjecture, just want to pick the brains of those who tried Sanwa/Airtronics M12, KO EX1 and 4PKSR, which one is more responsive?

Back over a decade ago when I was into gas onroad (the PCM days), I used Sanwa because I tried Futaba and KO and I felt its the most responsive amongst the three. Is it still true?
