IIRC though, the Zeo Power are supposed to grow stronger with time, which theoretically would make them the most powerful ranger team. So it makes no storyline sense that they'd still use the Turbo powers if that was the case, which the fan theory comes from.
The powers get stronger, but the zords were built by Billy. So maybe the zords don’t scale at the same rate. So maybe in the year between the starts of Zeo and Turbo, they had not gotten strong enough to fight Divatox. But again, the movie specifically mentions needing stronger Zords, not powers.
The Turbo team is like, the only team to lose. Powerset was the first made by Zordon. Idk, kinda seems like they made a tradeoff in hindsight, Zordon didn’t know his Zeo team who became his Turbo team would leave before they could beat Divatox.
But presently, yeah the Zeo powers are strongest. And it’s team is arguably the most decorated. They’re one of the longest tenured teams at their point if retirement. Having Tommy and Adam on the same team is OP, Rocky is no slouch, and Kat and Tanya are probably the most capable women in the series. Helps that the sentai is a military team which makes everyone look sharp in the costume footage.
I always said the reason we probably see more of Tommy in MMPR Green is because it’s the powerset he’s likely the most used to.
