Interesting question Tybalt, and to that I will refer you to a similar game-vs-game multi-factioned battle I set up some time ago here

And I also refer you to other similart battles here  and here

If you want to compare each individual unit, be my guest. If you want to compare weapons too be my guest. However I should say that if you just want to get down to it, you should probably compare the unit types:

AoEII Infantry vs RoN Infantry

AoEII Archers vs RoN Archers

AoEII Cavalry vs RoN Cavalry

etc.
