I prefer English but I've ridden western before and western horses will definitely teach you how to give the correct aids because they're so sensitive and English horses can be a bit dull. There's definitely stuff to learn from both disciplines!! I jut ride English, and have all my life and I love eventing so English it is!
English and western I have done western trail ridding
Both have great things about them that the other cannot do
I am an English rider, I jump and do dressage, but I have ridden a few western trail rides, and also the owner of my barn cuts cattle, so I have respect for both disciplines.
I ride English so English
