Hi Allen it is almost identical in speed envelope to those planes. That being very middle of the road and mostly dependent on how you set it up.
I run the Falcon 21.5x13 which is a tad slower than most.
I flew the Prolog last year and the Griffin the year before and the Nuance part of 2013.
This plane rolls better and snaps better than the others.
That's not to say anything bad about the other planes, It just does.
It's the best plane I have flown to date.
