PACT gameplay(1v1 unranked/10v10)

Hi I am a bit interested to play PACT divisions namely the Polish divisions, I heard 20 pancera is good for 1v1 or ranked, and desant is good for team games. What are the general consensus about them? Thanks. I am still trying to learn NATO divisions and getting over the wargame mentality, I like NATO divisions more but felt I should give PACT a try as well.
