Both are over priced, the first one in particular.
Ask for lots of photos from both owners, like is said above, it is impossible to even come close to tell conformation from one picture. I'm not sure I know what you mean by western, english pleasure? You are saying you want to do both?
As for your direct question, it is impossible to say with the info we have here, go see them, you will know.
I don't like when adds rave on about the horses breeding, generally means (at this price) it doesn't have much, if any experience. I don't care if its' grandfather won a million olympic gold medals, doesn't mean this horse is going to walk out of a paddock, in to the show ring and automatically win. The only way a horse and rider win is training and show ring experience!
DGW, I don't know what your talking about with the second horse. Her head is down because that is the western frame. She is actually being very obediant. Head down, like she is being asked, extension, like she is being asked, and look at her ears/face she is listening intently.
Go see them, take someone knowledgeable and impartial to point out important issues, in the end you won't need anyone to tell you.
