I honestly think you could go eitherway with both- on the pleasure side of things. Showing.. I don't know enough about confo pertaining to which discipline.. but I think your gelding would look awesome cutting cows, or under an English saddle doing lower level dressage.
As for your mare.. she's a cutie! I think she'd like hunter jumper, dressage, and maybe western pleasure.. but seeing as she's fast the western pleasure one may not be all that fitting.
Cute horses! I really like your gelding. He's built solid
