Combat tank: sacrifice armor or rof?

[vota dc]

When I modded Dune 2000 with Tibed I found this default values:

Ordos combat tank is 1800 armor,45 rate of fire

Atreides is 2100,50 rate of fire

Harkonnen is 2700,55 rate of fire

Now I want to know if the better rof of the Ordos tank is enough to rival the Harkonnen one.In that case the Ordos is the winner because the higher speed (yes,they are easily destroyed,but they destroy other units or run on infantry faster).

However the Atreides seems the worst:trading 600 armor for only 5 rof sounds bad.

Atreides have the worst combat tank (i Agree) but the harkonnen is the strongest and wins against 1 Ordos CT
