I have no idea what you want this horse for, but I'm going to assume you want it for jumping because most of the photos are of the horses jumping. If I was you I would personally get the grey in the first few photos. Not just because she is a stunner but because I think she looks to have the best jumping potential and she is is one of the most rounded horses going over the jump. My second choice would be the paint Daisy (is that her name? Can't be bothered going back to look!) because again I do believe she shows potential and with the correct traing or further advancing with jumping she could be quite a good little jumper. All in all it is your desicion and since I have no idea how you ride or how these horses move or what kind of rider they need. I truly think that you should go with what YOU think will be the best mount for you or what your instructor thinks.
