Which taildragger

So here I am in sunny (OK, heavy marine layer overcast) southern
California. Always looking for interesting/stupid/expensive
things to do, I see that there are a lot of outfits here offering
taildragger instruction, some aerobatic, some spin training,
some just tailwheel endorsements.

They use a variety of aircraft: Cubs, Aeroncas, Decathalon and
more.

Is there a significant difference between these different airplanes
when it comes to the initial learning about handling a taildragger?
