I don't know paint or app bloodlines. But imho I like the looks of Patches better. The way that Myspotsundectable is standing, it kind of makes him look toed out in the back. GOOD LUCK on your decision!!!
They both look too young to judge their conformation. Maybe its the way he is stand but the paint in the first picture looks like his legs are bowing. In the second picture of the paint he is nice and straight from his butt to his leg which is good but Its hard for me to say much cause they are just pictures and he isnt lined up but they both are way cute!
