I have both a Skorpios and a Hamilton, and hands down the Skorpios is a much higher quality bag. Not that the Hamilton isn't a very high quality bag, but it's just not in the same league as the Skorpios line.
Having said that, personally I am not a fan of flap bags - I haven't seen the Skorpios you posted IRL - but if that front bit is all flap it would drive me nuts having to lift that up every time I wanted into the bag. But if you like flap bags, I'd have to say go for the Skorpios.
I absolutely love the second Skorpios you linked to - the squarer one - GORGEOUS!!!
I think that's the one I want, now I need to find it since it's not made anymore, gah.
Plus I still want the Hamilton too, eek.
