I own a prestige Versailles. I would recommend the calfskin a over the leather because iy has so much more grip!!!
The top brand or just best quality that I've seen would be the equiline sj107 but that depends on what you would spend and what you need
The prestige is a great italian brand, the leather is amazing, but the "seat" is really deep in most of the models...i used to ride with a model named Sydney 2000, but than i sell it to buy a devoucoux.
Prestige are fantastic If you like thw deep seat, and Champions like M Robert, L Beerbaum and M Michaels B have collaborated to create some models: if they use them in the best competition so can we!
In my opinion the best saddles are French: Butet and Antares, but there are so many good brands!
I would die to try one of their dressage saddle and especially the Lucky Dressage Idol.
I had the DX when I was a rider of eventing. It is perfect for cross country, the quality of the leather is irreproachable. The saddle is flexible and light. You can have a real contact with your horse. The dutch olympic champion Hinrich Romeike uses this saddle.
I was not lucky enough to sit in a Prestige saddle but I know this is a famous brand and their products are very appreciated :)
I do not really know their jumping saddle but I have ride in a Venus K and it is really comfortable. I would love to buy a Prestige saddle.
