The Superstar EP, like any ideal first plane, is going to be limited in what it can do. You don't want a plane that doesn't give you so much capability that you're immediately in trouble as soon as you take off, especially if you're learning by yourself. It'll do loops, but it won't roll well due to the fact that it has no ailerons.
While it flies great on the stock system, it does have one major shortcoming: It's made of balsa and plywood. This is a plane that really needs an instructor to help you. Not that it's hard to fly, but as a newbie you will make mistakes. Balsa planes don't generally handle crashes very well...
Have you tried flying yet? It's amazing how fun it is to just putz around, especially when you're new to the hobby. Aerobatics are overrated
Now, don't knock the Slow Stick because it's just a stick with wings. You want a plane to learn on. By the time you've done a bit of "learning" on the plane it's gonna look like it was beat with an ugly stick anyway... You may as well start out that way, right?
The Slow Stick's bendy foam wing will take the brunt of most crashes, and keep the plane from sustaining mortal damage in most crashes. Plus, it's only $35. Buy two, they're cheap

You can replace the entire plane for about 1/3 the cost of a Superstar.
Don't bother with the Pico Stick. It's not on the same level as the Slow Stick. Much cruder, much smaller, less durable, same price.
