Przewalski's horse is probably my overall favorite.
Beyond that, I do quite like Colorado Rangers, Percherons, Criollos, Hanoverians, Icelandics, Drum horses, Dales ponies, Fell ponies, and a heck of a lot more-I just generally like horses. I miss riding.
Knapstruppers, any Spanish type breeds (Andalusian/Lusitanos/Lippizans,) and then a nice Warmblood. I don't think I could pinpoint a "specific" warmblood. Considering half of them have a mixture of lines and one horse could look nothing like its other siblings in the same breed. But I do like a nice Warmblood, any type.
Some of my favorites are Friesian, Arabian, Canadian, Clydesdale. Gypsy, and Mustang; but I'd have to say Paints are my all time fav.
The sweet old mare that I rode as a child was a red and white paint. She had a blaze down her face and the side of it zigzaged across her blue eye. She had heterochromia (one blue eye, one brown).
She was the most beautiful horse I've ever known. :)
