Go look at a Flow Drifter. $420 retail and with MORE tech than all but that Riders Choice from your list.
Others to peek at: Signal OG Flat, K2 Turbo Dream or Slayblade, Ride Berzerker, or Bataleon Goliath. For various reasons I would rather ride any one of those more than your current options.
Go ahead, drink that kool-aid.
