I think the bay is more feminine and refined, and she looks like she would make a much more elegant hunter. The chestnut has shorter pasterns (and the RF looks lumpy) so she wont be as smooth, and I doubt she will move as nice. She might be cuter as a gelding, just because her head and neck are not so feminine. She just doesnt scream elegance to me. But she is a Sabino, and hunters love that these days. I think her shoulder is steeper than the bays as well.
