Help me to choose...

Hi, can you help me to choose between F1 2014 and F1 2015? Yeah I know they are old games..

I played different F1 games starting from the 2009 on PPSSPP, F1 2010, '11, '12, and '13 but now I want to try something new. Well speaking of something new, these are the only F1 games I can play on my "potato laptop" so I need your suggestions guys. I'm currently using this Asus X441S which is very limited on gaming and I'm surprised that it can handle those mentioned f1 games above pretty well
