They all can be very accurate shooters. I have both a 20ga Tracker II and a 20ga USH. With lightfield hybrid express 2 3/4" the Tracker will shoot a 3 shot clover leaf at 75 yards and the USH comes in a very close 2nd with 2 3/4" buck hammers. The main difference is weight, the USH is a heavy barrel. These two are definitely going to get entered in the postal shoot! The other thing is the USH is drilled and tapped for a scope mount, I had my Tracker drilled and tapped.
