I have all the higher end direct drive pedals except this new dw. Trick, check. Axis, check. Demon Drive, check. Yamaha, Check. I gotta say, the biggest thing for me is the footboard length. The feel, in my experience, just aint much different among the pedals. I switch theM back and forth all the time just about every day at home.....The jojo Mayer, although strap drive, may be the smoothest of all. But it does not acclimate to heel toe as well with my size 13s.
There is no best, but the Axis Longboard X is the one that stays on my kit longest...the demon drive a close second....and for reh and gigs I have done I just take the p930 and it is far better than good enough. I'm not good enough yet, but any reasonable single kick drummer will be able shred Bonham or mcbrain on the p930.....
As a collector, I may pop for the dw, but as a player, single pedal, I can't imagine it will provide any playing benefit over the Axis. For guys with larger feet like me, if you can't operate at very high levels with the Axis longs, I think something is not right with the technique. Those things shred.
