I'm torn between the Great Planes 40 size Extra kit and Great Planes 40 size Cap232 kit... or am I???

I'm looking for a relatively aerobatic/3D kit, not an ARF, between 40-60 size. I feel that i need to challenge myself with the experience of kit building.
This is off topic to the subject, but whenever I see a cool new plane come out it's always an ARF and not a kit, but I guess the manufactures are just giving the majority what they want.
Back to the 2 planes I mentioned above, are both of these planes equally matched if they have the same engine? I want to be able to have a plane that can hover (3D) along with scale aerobatics. Do you believe that the weight and design difference between these planes has an impact on that aspect?; Airfoil, wing placement, etc.
I'll take things slowly though; I'm not in a hurry. I will most likely save up all the money I can (I wonder where I will work this summer

)and purchase it when I can. By then I'll hopefully have enough for an engine too. I might be thinking too far ahead anyway, but we'll see.
Thanks for your time and input!

BTW, which engine is good for what I want to do in the planes I'm interested in?
