I have a used OEM jdm ITR clutch that I plan on using when my stock clutch starts to go (actually its already going). In fact I plan on putting my flywheel in there when I put my 'new' clutch in fairly soon.
I like the feel of the OEM, and as long as I can find a reasonably priced one (slightly used?), I'll stick with those.
If I am in a bind and need a clutch (non oem), I'd get the Action 1ms.
