Nicolas, I'm building an RV-7A and I'm not even a pilot yet. I'm all for getting some rides in each one, that will help you. But I think it would help you more to determine your MISSION and then your decision will be easy.
So what made me decide on the RV-7A? Three things.
First, I won't be a new pilot or a low-time pilot for very long. I'm looking long-term. So build the airplane you want, your limited hours won't matter a few years from now.
Next, I want to go fast. My wife and I are looking forward to a lot of cross country travel. This gives the 7A a big advantage over the RV-12.
Finally, I would like to do some aerobatics once in a while. My choice was easy.
If none of these things matter to you, the RV-12 is a great airplane. I'm sure you'll love it! I hope this is helpful.
