From what I find online the Moab qualifier is a $49 add on to a 4-day (or 3-day for less $) Rawhyde event. The SC qualifier is $200 for the BMW qualifier only, no guests, no spectators and no other activities. Probably not fair to compare the two events on price alone as they seem to be different formats / events.
Which one's better
That probably depends on you. I'll bet they'll be more
at Moab. YMMV
