Let's just say that there's "something about a Cub."
Once you've learned to fly, and to take off and land well with a taildragger, then a Cub is just a nice "Sunday" flyer. They're gentle, honest, easy flying planes, but they HAVE to be flown. They require coordinated rudder in turns, and they look truly LOUSY in the air when they're overpowered, and they almost demand a four stroke engine. A Cub with a two stroke just ain't right, and it's an insult to a classic.
A Cub is also an ideal first scale plane. They're well known, easy to build and to detail, relatively easy to fly, and generally a "charming" airplane.
It's difficult to describe the reason for their popularity, it lies mostly in it's aesthetics.
