I agree with Kayty. But , for a you, where you are in life, perhaps doing Western for a while will feel more comfortable and be more "fun". Dressage, if done correctly, can take a long time before you are doing the more obviously exciting manuevers (if any of it is exciting , to some people). I , too, like the attention to minute detail and the focus on the quality of the movement as it helps you build you way to the next movement. But, if you are young and you really just want to learn to have a decent seat, have some fun on a hrose, be with other folks who want to cut loose and have some fun with horses, then maybe Western is better.
