I have the Annice with the Genesis, so I'll talk most about it, since it's the only one I have any real hands on information with.
Best purchase ever!!
I've thought about used Antares, or CWD's and such, but I'd honestly rather have this, with the Genesis. As long as the tree angle is correct, then you can fit it to any horse in width. I'd rather have a mid-range saddle that fits my horse like a glove, than a name brand saddle that makes me cringe at every ride for the safety of his back.
My gelding is very broad through the shoulder, wide set, and semi-curvy.
I'm pretty sure all MT models run on the curvier side.
The calfskin leather is pretty delicate, but it's not really a problem. I've gotten some pretty deep scratches on it, due to my neglect, but a quick conditioning, and they aren't visible anymore.
The seat is comfortable. It's very sofa-like, but without drowning you. I'm just as solid down in a full seat, but still have no problems getting up into a two point.
I'm not sure about the Aachen, I'd wish I'd sat in it when I was at Dover last. :/
But the Annice puts me in a great position for hunters/Eq. Very balanced.
If I rode more dressage, I'd definitely get the Aachen as well. But as little as I do, my Wintec suits me fine.
I've loved having the Genesis system. It takes literally two minutes to refit it to any horse.
Toulouse, in general is a good, well built saddle. It'll last you for quite a while.
