Frames per second counter in-game

Hello, I know this has been asked so many times but until now I have seen like 10 different scripts and I’m not sure which way is the better to get the frames per second in-game.

Can somebody tell me please which way is the better and correct way to get the frames per second In-Game? (Preferred for Unity 5)

Thanks in advance
