Haven't tried the Stage 2 but I can speak for the Exedy Organic in my car right now and it's all positive. As stated previously, pedal feel is a big factor for me and when first using it, it does feel stiff and takes more pressure than the stock, but after becoming used to it, it's second nature to me.
Also, I have never experienced slippage in the two+ years I have had it. It grabs at any RPM I can throw at it. Good buy from
