Hi Lily, I find Bates and Equiline dressage saddles to be quite minimal and slick ;)
The key is not the brand but an adapted saddle to you and your horse. The only point you should reall care about it's that it has to fit you horse, for its comfort and yours as well. Otherwise you may hurt it or yourself or have a bad position and ride baddly. To me, you better ask a saddle fitter or at least your coach.
