Every faction has a unit that is better than these guys. Common troops too. You don't have to wait for nox and if yours just comparing stats,.... yeah these guys would be the bottom of top tier. Assuming 500 is the high bar.
But as I said this is a phase 3, end game unit, where you are an established king and money isn't a thing. Where your dropping 200k on a lordly something to put on your companion or these guys. 10k is what to you make waking up.
What's the saying (Wine glass in hand, pinky out, extra snooty and snob status in full show) "If you have to ask the price, then your probably not making enough to be shopping here son."
Rude jokes aside. Everyone finds value in different units in different ways. That's one of the awesome things about this mod. Enjoy however you wish.
