Appearance-wise, I've always been a softie for the big breeds, although there's also a Paint-QH gelding at our current barn who has a nearly-perfect personality (just needs work getting possessive against other horses with his food).
However, our current gelding, who was also the first horse we bought (our second mare unfortunately passed away), is as perfect as perfect can get, at least for us. He actually wasn't what I'd pictured for us at all, but he "chose us" early on and worked perfectly.
Thoroughbred
23
Chestnut
Connected star, strip, snip (not wide enough to be a blaze), one white front coronet and one half-pastern
Now-retired English (ex-racer, was used for eventing)
Male (gelding)
He's been polite and considerate since day one, he's been particularly attached to me since day one, and he's been worked with enough in the past to have good manners and tolerate all the "first time owner" mistakes we made when we first got him. We were told beforehand to never get a thoroughbred until we were ready for them, but he's been wonderful proof that you can't label an animal strictly by its breed. He doesn't crib Any "kicking" he's done has been minor protesting with a specific foot he's always finicky with. It's never aimed to hurt us and was easily corrected. He occasionally gets a little bite-y with his halter (if he thinks we're not moving fast enough), but he listens to corrections and stops when told. He stands for the farrier, vet, and grooming, trailer loads well, and tolerates all the hugs and kisses we plaster all over his face and neck. My mom worries about horses that don't have blankets or refuse to come in in bad weather. Foxy needs blankets due to increasing age and short fur, and he rarely wants out for more than a few hours.
He takes medicine and wormers well, and he (knock on wood) has never had problems with weight or colic. While a bad leg means he can no longer be ridden, he's still a gentleman and tends to be loved by anyone no matter where he goes. At place where we bought him from, the stable hand stopped and talked to me about how good of a horse he was. At one of the barns where we boarded him, we had complete strangers come up and ask if he was for sale (heck no!). Our current barn's owner thinks he's great, too, and he's always easy for her to move.
