Replying to Look px12 Jibs, or Marker griffons?

Alright so the original binding I bought for my skis were the Marker griffons, but after 2 seasons, 2 broken breaks, and a missing slidey thing on the toe piece (what ever the hell it is called) I decided to get a new pair. I went looking and found a brand new pair of look px12 Jibs for 130 dollars, did some research and decided i probably wasnt going to find a better deal. Well i just got back from my local shop to get my new bindings mounted. When I got there the guy that helped me out proceeded to tell me that the griffon was a better binding and asked why i was switching them. Needless to say that "fuck me" feeling came over me and i just responded with "Ive only ever ridden marker and i decided it was time to switch it up" Which is true in that that single pair of bindings were the only pair of bindings ive ever owned. SO, Im just wondering if the markers really are better or if the guy at the shop just has no clue what he is talking about and is just trying to promote markers because thats the main binding they sell at their shop.

SPARK NOTE: which is better?
