I'm an English girl.
I have nothing against Western. I actually quite enjoy it when I don't have to ride a horse that insists on trying to graze and slamming my stomach into the saddle horn, and I'd really like to get a Western saddle for trail rides when I have my own horse. It's nice for long distances.
That aside, I just love English. My aunt and uncle used to breed and train horses for the local hunter-jumper community, and they were fairly popular. They bred Haflinger-Thoroughbred crosses who were good hardy little horses that jumped well and were just good, versatile horses, and they also bred pure Haflingers and Thoroughbreds as well, and they ran their local Pony Club.
I grew up going out to their farm at least once a month. They used to let us ride around on the ponies- never fast, I never jumped, but I rode a lot when I was younger. I used to follow my cousin (Who's thirteen years older than I am) around while she groomed and cleaned tack and fed the horses. I was terrified of the horses up until I was three because they were so much bigger than me, but I loved them nonetheless. One of my favorite memories from my time out at their farm was sitting on the back of my cousin's mare while she led her down to the stream to splash around with us.
I started begging my parents for a pony when I was three. When I was oh, four or five, we went to watch my cousin compete in a local hunter-jumper show for Pony Club, and I was immediately hooked. I wanted to learn to fly like she did, and I started begging my parents, and it took them three years to give in and let me start taking lessons.
That's really why I love English. Western has its advantages, but when I'm riding English, when I'm jumping or galloping a cross country course (Which is my absolute favorite event ever, cross country is just incredible), I feel like I'm flying, and I love it.
English isn't more rigid than Western in any sense. It's different, but it's not harder, or easier, or anything. It's just different. There are some riders who are in it to earn the ribbons, but I'm not one of them. I'm in it to be with horses, and if I get a few ribbons along the way, then I'm definitely okay with that, but I ride because I love it, not because I want a wall covered in blues. I like showing, it's fun and I enjoy it, but you can be a backyard English rider just like you can be a backyard Western one (I'm not saying I am, I do take my riding seriously, but not to an extreme).
And trust me, I've done everything you can do in an English saddle. I've galloped at racetracks, jumped, barrel raced extremely slowly, gone on six-hour trail rides, fake jousted with a friend, played polo with brooms, all sorts of things. It's so versatile, I've had so much fun with it, and I'd never trade an English saddle for a Western one. I'll take flying any day.
EDIT: And while you *can* jump in a Western saddle, it's not advised because there's something called a saddle horn which gets majorly in the way.
