I wouldnt buy either, I had an Exedy Stage 1 and after around 5k miles one of the torque springs broke out the casing as far as i'm concerned the F1 clutch is an even cheaper option.
I'd just buy Honda OEM clutch, Some will tell you Exedy / Daikin made the OEM clutches for Honda but apparently was Fuji Carbon who made the ITR ones. (not 100% on this).
I will say I prefered the feel of the exedy over OEM as it bites harder but i'd rather have reliability any day.
