DR1Driver is completely correct. Neither one is harder than the other, just different.
I'll disagree with both of you, respectfully.

In general, I think trikes are easier to keep going straight on takeoff than tail draggers. Also, with many (most?) tail draggers there's a need to hold up elevator during the taxi and initial part of the takeoff run. Keeping to keep a tail dragger straight and gradually letting off the elevator as it picks up speed make a taildragger a bit more complicated.
I see people all the time here on RCU (and in real life) get wrapped around the axle because they are afraid of a taildragger. They aren't any harder than a trike, just a little bit different. Build whatever you like the look of.
I agree that the challenges of a tail dragger are often overstated. Most aren't difficult, although some are notorious for having bad habits (Cubs for example).
