We do Western/pleasure riding and you can't beat a Paint (or a QH). Low maintenance, easy keepers, great dispositions, willing, smart, and can go just about anywhere.
I posted TB but only because I have one myself, it obviously depends what you want to do with your horse, my TB is a showjumper, but if your looking for a horse to do western on i'm compleatly unqualifed to comment as I have never ridden western myself.. although TB's are fairly versitile they can do western can't they??
Not easy to say, you didnt say what disciplin, nor anything. Nor your experience, hieght etc. For a good all rounder go for a QH, they are good all rounders but if you want to do a disciplin like jumping, dressage, eventing etc, Anglo Arab, WB, TB, etc. :)
