Muzzles are crowned to make it more difficult for the owners to ding the ends of the rifling. The traditional crown does this well.

Match type crowns prioritize an even exit surface that evenly distributes the powder gasses and presents minimal chance for bullet influence. You cannot clean this type of crown from the muzzle and it's comparitively easy to damage, with bad effects on accuracy.

As noted above, most of us wobble enough on our own, the type of crown make little difference.
