I have Freerider Recharged and Velocidrone. I have done over 90 percent of the time in Freerider. For some reason it just feels better to me. It has a demo version that you can check out for free but it is a little sluggish on purpose. It is only 10 bucks to purchase which I think is quite fair. You can even create your own worlds to fly in.
Velocidrone has a bunch of quads to choose from and more scenery. Its about 17 bucks.
I would advise using a real rc controller with the sims as it really helps in building the muscle memory on the controller you will actually use while flying the real thing.
This is a clip of messing around in Freerider. You can see what four of the worlds look like.
I'm still a bit of a noob myself...
