Best European show to attend?

[CDinFrance]

We are in discovery mode and wondering what shows are recommended for campervans and accessories. Based in France near Geneva so we are pretty central, and have good Easyjet connections. From my limited research, it seems like the Dusseldorf show is very good. There is also Paris Bourget, or the U.K. national show. Do most of the accessory dealers do the big shows?

Suggestions welcome.

Uk shows I really like:

Camperjam :- great fun, entertainment, camping as well as the massive market.
Campermart Telford - One day only, indoor very busy show.
Stanford hall - usually a nice show with lots of displays of vehicles of all shapes and sizes.

I can't decide if I would fly to visit them as they are nice and close for me.

Allegedly Dusseldorf is the largest in Europe. I am thinking of going but nothing certain at the moment.
