There's some confusion here.
Albion's sword is the Turin St Maurice sword, which is from the 13th century.
The MRL and the A&A sword replicate the coronation sword of the Holy Roman Emperor, and from the 10th century (though the engraving was added two centuries later). Same saint; Different sword.
As I understand it, the Turin sword was a cavalry sword, and thus had quite a bit of blade presence for sweeping cuts from above on horseback to footsoldiers who weren't standing there parrying and riposting. When thought about in that context, it makes more sense for the balance to be what it is. The other St Maurice sword, being a coronation sword, probably wasn't designed with balance or proper handling in mind.
I suspect the A&A more closely resembles the handling characteristics of the original (just guessing, as I've never handled the original), but the MRL one probably has a more "lively" feel so as to cater to the modern market who doesn't care about how accurate it is. The MRL one looks pretty "chunky", but the price point is certainly reflective of that.
