Which creatures from the alternative upgrade options do you choose?

I have a clear opinion only about Necropolis so far. 1. Upgrades with equal efficiency – I gather Warriors until I have 300-400 of them; they are tougher and easier to keep alive. Otherwise, archers are constantly being targeted:D. After that, I transform all of them into archers, because with that many, they are at least somewhat effective. 2. The new zombies are definitely better – they are tougher (and they are not attackers, but a shield), and their aura is more useful than the old ones' ability to inflict weakness on the attacked. The poor things don't get to attack that often:D. 3. Again, the new ones are better in terms of parameters. As for the abilities of both, they are not that important. 4. I am all for the old vampires – they are more reliable and combat-ready, and the new ones' sleep ability is a rather specific thing. 5. The new liches are great – although a cloud of old liches is cool, it's not always the case that the enemy stands in a tight group. But raising your own losses with a strong detachment of liches is very valuable, even a strong hero won't be able to raise as many as a detachment of 50+ liches. 6. The old ones are better in terms of parameters, but the new ones' ability sometimes works well; the result is that I still prefer the old upgrade. They are powerful. 7. Astral drakes are definitely more useful than spectral drakes, and I now use them. But the design is terrible!!! The thunderbirds just took the old model, desaturated it, and made it semi-transparent. Oh, designers...
