The reality is I hardly use it, but every time I've needed it it's been worth its weight in gold (for example, when I went to oversized throttle bodies, I didn't have to do the pedal dance... I just had to click a button on my cell phone and it re-learned my idle).

Throttle response for me is decent. From everything I've read, Seb seems to lean towards very abrupt throttle response; stock car has no throttle response; and I'm probably somewhere in the middle (drastically improved over stock, but still linear, as in the more I push down the pedal the more the TB's open), though I'd have to try one tuned by Seb to give truly accurate feedback.

I'm still slightly over-revving as well since I just installed the RJM Sunday but I was much better on my drive in to work today. Love that pedal.
