Clear question nfs mobile vs asphalt 9

Clear question I never played nfs mobile. I always played asphalt 9 and there is reason for it the thing is every where I see in tech youtubers and all use this game to test the mobile phones for performance and all. I have never seen people using nfs this was the reason what I am thinking is the game is not that level compared to asphalt. But I want and from nfs players which is better and why I will be happy if u can explain me by comparing them.
