It is absoultely true that tailwheel skills make a better pilot. It is also true that those skills are harder to acquire, so you might take a bit longer to solo (i.e. you'll spend more money).
Most people learn on nosewheel aircraft, and once they have the licence, decide if they want to spend the extra on the tailwheel.
Aerobatics, Historical aircraft, Glider towing, Crop dusting, some Bush flying all use tailwheel. Are you going to be doing any of that in your forseeable future?
