What is better: quality or quantity?

I start by building as many unit-producing buildings as possible, I don't do any upgrades at all, and I focus on waiting for the capital and am guided by the availability of resources, trying to ensure that no day passes without an upgrade. As the week progresses, I try to build at least a Stronghold. And then, on the first day of the second week, I buy as many of the grown units as possible and start crushing the neutrals. And in the game, especially in campaigns, I always prefer experience to gold from chests. So, I have enough money and I train units regularly. Another feature of my gameplay is that I have a separate hero who stays in the castle and accumulates peasants or upgrades for this unit. By the end of the 3rd month, they generate about 2000 per day – like an entire castle. And I only train swordsmen into monks. So, I have enough money and a strong army. I like ranged attacks!
In the end, I prioritize quality.
