Two things
1) An accurately placed three pointer is A Good Thing
2) There are times when wheelers are very useful; gusty conditions, or when the aircraft design demands it. There are also times when wheelers are not good; at least one Tiger has nosed over this year due to a misplaced wheeler, and not all taildraggers are happy being wheeled on, unless you have equal accuracy to that required for a three-pointer.
I'm no expert, these are just a couple of things I've learned so far.
