Groyce,
As writer and owner of the ACS patent you might expect that I've tested them side by side and I have. I've said many times the difference is like comparing a light, nimble, and tricky Ferrari (A&H) to a blown, hammering, and sturdy Corvette (Dryad).
I designed them both and like them both very much. Performance-wise there's essentially zero difference. There are lots of differences in the two designs but they both go from zero to sixty in 3.8 seconds (to stretch the race car analogy a bit farther).
