Analysis vs key moments

Sort:
Fokuskeks

In my (white) 15. move the engine analysis says Nxf7 is the best move. When I use the key moments function it says 15. Nxf7 is a mistake (?) and Rxf7 is the best move. So I wonder if the analysis function and the key moments function are using different engines or what is the difference? And which function can I trust more?
