Taildragger is fun and challenging and if you have the opportunity, it's cool.
But I'll say that it doesn't necessarily make one a better pilot. If your instructor was real good about making sure you land on the centerline and aligned every single time, in every condition, it's not going to be very beneficial. If you just "got by" during training, then a tailwheel can wrap you up real fast and get you into trouble taxiing, taking off or landing. Part of what makes it fun is you have to "reverse" what you normally do during landing, but that's not part of the rudder control part and it doesn't make you better, it's just a different skill. That's where my learning curve was, and once you got it, it's kind of "over" IMO. Rudder is just to keep the plane straight, like always, you have to possibly use it a little more, but if your instructor beat this into your head already, it's not a huge deal.
