They can mow down Mamlukes and Swadian Knights, outrange Rhodok crossbows, and can break down Huscarl shields like they're nothing due to their insane range, accuracy and spammability.
Especially if you have terrain to your advantage. Tbh I think Vaegir top tier archer spam is the best in the game for taking over the map if we're not talking about auto-resolve fights and AI vs AI fights. IMHO Nords are slightly better (I like to be aggressive in sieges). Success of defending the walls heavily depends on crossbowmen since the spearmen here act only as meatshield for them. In defensive siege, Rhodok crossbowmen sure can outclass Nordic archers, but their main target would be Nordic infantry pushing on their spearmen. In offensive siege, spearmen won't be able to breach the walls on their own and crossbowmen can shoot only non covered units. Using crossbowmen as support can offset it a bit but even their crossbows are not enough to deal with huge shieldwall. Sure, their spearmen can stop and take down cavalry but in 1v1 combat they're not that good (apart from having high defence). Rhodoks are awesome in defence but lack the damage output in offence. Rhodoks have better crossbowmen, Nords have better infantry. Then you shouldn't have asked :D however if you're up for some discussion.
