For 3D I like the Edges. They have few if any bad habits in very slow flight. For tumbles and spins it is hard to beat a CAP. The Extras fall in the middle.
If you want 3D look at the Edge! I like the flight of the AeroTech and the Carden Edge. They are very sturdy and can take a lick and keep on ticking, most of the time. If you go with these you won't go wrong. If you are a "builder" the Carden is a great kit. If you "can" build the AeroTech goes together much easier being all laser cut. Both of these birds fly great at 28-30 pounds with a 100cc twin on the nose. Some people are totally hung up on being the lightest, it may help the wing loading but it has its trade offs as everything does.
I've never ever heard anyone say "Man I wish this thing was heavier" or "Man this thing is just too light"
