personally for me it was the OG 100t, the one at berlin
100t m3 - they had skills and experience, was the most complete team in m3
Prx - Skilled and playstyle are very unique and fun to watch
Sentinels after sinatraa left - aggressive and dominating style was fun to watch until they loss, but they still trash talked which was fun. Most toxic team which is why I like them.
2022 m1 Zeta - personalities are great.
G2 champions - trash talk = fun to watch.
