I have a Hori fighting commander but I prefer the standard NEC 2 button pad.  Since the early '90s I've always associated PCE/Turbo games, the systems and the whole experience with the standard NEC pad.  I use the Hori mainly for 6 button games and I do prefer it over the Ave 6 pad.  The Hori is an excellent controller but I'll never replace the trusty NEC 2 button pad.
