Survivor - China (Season 15) is a good one to start with. It's "modern" and gives you a lot of places to go, but with really interesting characters.
AHS - Good to binge watch a whole season at a time, but not the whole series. Just start at 1 and go on through.
Not a huge fan of Amazing Race personally, "Flavour of Love" you can mostly just watch Tiffany "New York" Pollard compilations online and get the jist of it haha.
every season lmao
