I "learned" dressage alongside my current horse, and while we are not doing badly twelve years down the line, I spent a lot of time screwing her training up, having to fix it, then screwing something else up, having to fix that, and so forth. If you haven't a clue what correct impulsion, collection, bend, etc. should feel like, it's a long, frustrating road figuring it out, even just to get a horse doing Second Level well. I got so fed up I quit competitions and now just school and mess about with dressage for fun. Had I a schoolmaster horse and she a schoolmaster rider, we probably would have gotten much further but we were the classic case of the blind leading the blind. Eleven or twelve years is a long time to wait to have a horse who goes correctly! It was fine, though, and of course it has been enjoyable learning experience, or rather became so after I quit competing.
I've known plenty of horses who weren't "fancy" but who were trained correctly and could teach you how to ride the movements and have the horse on the aids. None of the horses you have posted seem to have significantly more dressage potential than your appy, from what I've seen of the videos you have posted of him, nor do they seem to have more training in the discipline. If I was in your shoes and serious about finding a dressage horse, I'd be looking for something that had considerably more training than Mr. G and/or considerably more potential, and not be bothered with what the riding club thought.
