Replying to Marker Griffon or Look PX12?

Ok so right now i have the Look PX12 and they seem to work great. Im buying afterbangs next season and was wondering which bindings to get.

I havnt had problems with my Looks but i heard Marker Bindings are pretty sick.

Sooo my question is should i just get Looks again next year or should i spend the extra money and get Marker Griffons? Is it really that big of a difference?

Oh ya im 5'9, 130 pounds, I wear 28.5 boots and im an intermediate skiier

Thanks K+++
