Well if you have the Money , the flying area and an instructor go for the apprentice.
As you say the radio , lipo and charger can be used down the line.
The apprentice is just as durable as the super cub.
The apprentice is probably alittle bit harder to fly than the supercub but if you have sim experience and an instructor it should not be a problem.
it has ailerons - good training for future aeroplanes.
also it is a tri gear as apposed to a tail dragger so it is easier to land.

any questions just contact me.
good luck and welcome to the most obsessive hobby ever.
