If you can land a trike competently, then I fail to see how taildragger skills will make you better at landing a trike, as they are redundant.
If you fly a tail dragger, then you need some extra finesse and technique.
Fundamental lack of appreciation of what makes a good landing there. A conventional gear ensures you fly a fully held-off (or accurate wheeler) landing, else the aeroplane will object, quite violenty if you ignore it.
With a tri-gear, you don't have to, so most tri-gear pilots don't. Unless they also fly conventional gear, in which case they will.
That's how tailwheel experience makes you a better trike lander. Of course, a tri gear-only pilot could make a correctly held-off landing, and some do... but observation at any GA field will demonstrate that most don't.
