1. If you are fairly experienced with your trainer and you can takeoff, land, and do touch an go's with no problems and are performing basic aerobatics then my vote is for the Sig SE. Keep the throws low and you will love it and as you get better increase the throws and it will get wild.
2. If you are still struggling a little to make good takeoffs and landings or don't feel confident in you flying ability then I would go with the Sig Fourstar or something like it. It has the ability to perform aerobatic maneuvers but will slow down and land nice and easy. The Sig SE is not as easy to land and can get you in trouble if the throws are not set real mild.

Also both of these are tail draggers and not as easy to takeoff as a tricycle gear plane. World models and Thunder Tiger have low wing planes with tricycle gear and most Stick type planes can be set up either way (you can never go wrong with a stick)

Just My Opinion
