I have/had three of the above mentioned planes. The real answer is how much can you afford, you will probably go through several/many planes. How big is your flying field? What do other guys you know fly so they can help you with set up. Computer simulator speeds up the learning curve. Search out 3 D web sites. www.flyingcirkus.com has 3D university with good down loads of 3D flying basics. There are other websites that have information on aerobatic trimming charts... learn them and use them. You must learn to set up the plane correctly. Get really good at basic aerobatics. So far my favorite is OMP 46 Kantana with Magnum 53 (cheapest, I have destroyed 4 engines in crashes), 12-4 prop, Hitec 475 servos. Do not try to skimp on servos. Profile planes are easier and quicker to build, and generally fly great. Generally, so I am told, the bigger planes are easier to fly, unless you stick on too big a motor. Simple Plastic Airplane (3D) Designs are the cheapest and most durable, good for learning basics, but an advance pilot will feel they don't fly as well as more expensive kits.
