Welcome to the forums.
I've flown the F-22 but not the Sportster. I have flown plenty of planes similar to the sportster. The F-22 is fun to fly but it is not a "go to" all around plane. More of a niche. You will probably get more enjoyment, in the long run, from the Sportster.
Good luck with whatever you decide. Keep us posted on your progress and share pictures or video whenever possible.
