The original Most Wanted (2005) is very good in my opinion. The new (2012) is not so much. I have not tried Heat (2019) so far, but based on the first look, it is similar to Carbon (2006), which is very good. As I remember, the last Need For Speed I tried was the Rivals (2013), and currently this is my favorite.
Good luck and have fun.
Have a nice day. All the best. Greetings and much love from Hungary.
