Which one do you prefer?
Zeta was always good, even DRX had backed them up after their loss against them in this event. KRU though was different, they took out Sentinels in a kind of 'no respect' fashion which imo was necessary. And then when everyone thought that it would be all EMEA semifinal, they took out a well coordinated Fnatic team. Their match against Gambit is the best Valorant match ever played in an international LAN event so that speaks for itself.
Also it happened at Valorant's first ever major so it weighs more. Zeta is great, no disrespect to them.
KRU forced everyone to play their own game at times which favored them in most instances, which resulted in them eventually falling to Gambit juggernauts who kept playing their own game and punished KRU. It had its moments of greatness and was joyous to watch but from a strategic standpoint it was nothing to write home about.
ZETA showcased many moments of brilliance throughout the whole Masters. They adapted to every opponent and countered them to perfection. Every single map they've played, they would chip away map control, piece by piece and slowly beat their opponents. They got no big names, star duelists, hard carries or anything like that... Just brilliant defaults, executes and adaptation.
ZETA most definitely!
However, the hype around KRU at the time was enormous and not to be underestimated.
