Uncrashed is the best FPV sim I've messed with so far. I like that they let you configure enough aspects of the quad's performance that it's possible to approximate your actual rig. I have a nearly spot-on (in terms of flight characteristics) virtual version of my 3.5" that has been a blast to practice on. Pair this up with a ton of really great community-built maps (many replicas of IRL environments), and it's difficult to top, imo
I honestly love chasing the cars and stuff when I do fire up the sim. Uncrashed to me is more fun than liftoff. Most maps feel small after starting with uncrashed as well.
I feel like velocidrone is floatier compared to real life. I found the best setting in Uncrashed is 12-13 on the gravity setting. I have about 100 hours in each sim messing around with different settings etc. I have a video playing Uncrashed you can check out as well.
I have them all and find myself in velodrome 95% of the time. Best physics by a mile and I while the large maps are fun to explore and stuff, the race oriented maps in velodrome I find explode my skills a lot faster than the other types of games/maps. Plus there are so many it keeps me more engaged. I’m saying this as someone who prefers to fly freestyle irl.
