I like all three snakes. They're all unique in their own way, I'm not a perfectionist, I like all snakes for their own unique patterns and personalities. Or any animal in that case!
The attitude about the snake you didn't like for whatever reason kind of bothered me I guess, even if you don't feel that way now. I own a normal ball python similar to that and she's perfect and beautiful to me. I'd be devastated if I ever lost my little girl. I can't understand how anyone could just decide something at first glance then toss her out. Even if you don't feel that way now... the fact that it was just considered for even a second bothers me.
But whatever, I hope you give her a good home whether it is with you or someone else. She deserves it just like any other snake.
If you keep her, I don't want you to keep her just because you feel bad for her or something, but because you really want her. Other snake owners would genuinely want her if you offered to give her away. I'd take her, too.
All three look great IMO, you got a great deal. Hope I didn't sound like I was attacking you, I was just stating my opinion on this.
