They all are great brands, each has their ups and downs. I would choose they saddle you and your trainer think fits you and your horse best.
Butet is better known and a more luxurious, higher quality saddle to have. They're the 'it' saddle in NZ
I’ve ridden in a CWD, Devoucoux, Antares, just not Butet. Personally, I like the CWD the best just because how it fits me. The Antares has the better quality leather, but if not taken care of it can ruin a lot of breeches. The Devocoux, I personally hate just because they are really hard to sit in and they have made my horses back sore.
