The new site might be appealing if you are light weight. But then how do you get your tent back. :-) At around twice the price of MB and Houx and three times the price of most of the other sites I really wonder if it's good value. It does have the edge over Houx in that it has a Track view. I notice it also has Electricity.
On the down side they will rigourously enforce the 30m
2 area limit as they are putting up the tents. Note also the space is 5m
2 less than what your allowed in the other sites. (We know how creative we can be with that.

)
There looks like there is a much more comprehensive shuttle service too.
The new BSJ site looks interesting. 3 cars 2 campers or a Bus. For sure if there is a group of you it may be worth considering.

2 of grass now your talking.
