I have avenue 6 and standard pc engine pads, they are ok, functional, not great ergonomically, I also have snes/sfc hori fighting command ( pc engine version are usually pricey cos it's not common), it's much much better in d pad responsiveness and ergonomics, very very good
But hori has always been well known for the leading edge in controller design (I have over 10 hori controllers/joysticks, including ps3, ps2 wireless, ps2 wired with headphone extension, hori wii classic controller - great for wii emulators, ps1 fighting command, ps1 classic non analog, 2 ps2 hori sticks and 2 ps3 wireless hori/wired joystick ) some of the hori controllers reach silly prices, ie, n64 hori mini and gc digital controller, which I think is more money than sence
