I think an important part of experimental has been barely touched on here. Performance. Plain and simple, performance in homebuilts almost always far exceeds the certified world. Case in point, my friends Symphony. Compared to my Glastar its a slug in every way. The symphony is a certified version of my Glastar and yet it cruises 25knots slower, takes off in twice the distance and climbs at half the rate with less payload and less range. And on top of that it has to have an annual by an a&p with an inspection certification. Then, the repairs and maintainable is four times as expensive just for parts. I had my fuel injection servo rebuilt on my io320 and paid $800.00 for the exact same rebuild by a certified shop that charges $4,000 for the same job with a yellow tag!
Then, as mentioned, freedom. You are free to do make sense things to your experimental like LED lights. Couldn't even put them in the cessna I had, the A&E wouldn't let me replace the dome lights with them! These silly rules are gone with experimental aircrFt. The downside of this is that you are also allowed to do stupid things with your airplane as well. As long as you feel confident you won't do foolish things to your experimental aircraft I think you are likely to be very happy with the move. Welcome to our world.
