Upgrade or alternative upgrade?

Level 1: I need Landlords more often because when there are many of them, the chance of a double strike increases. Right now, I'm playing as Humans with 90 Landlords, and I've only had a single strike once (1/9), all the others were double strikes. And with Militia, IMHO, the "pushback" ability drops much more often, but if it does drop, it's great! Level 2: Always Archers!! 45 archers have a high chance of destroying a large number of troops with a single attack, and if they also have max luck))) Level 3: If there are many swordsmen, then Zealots, because 1 unit will definitely kill them))) Knights can also protect others, which is also good! But only if it's for defense. I don't know about the levels above, I haven't played in a long time, and I haven't reached them yet.
