I know this will sound completely biased, but how can they even get to their mechs when they are swarmed by hundreds of clones, blinded and slashed at, stuck to the ground due to gravity, burned alive by feather missiles, electrocuted while being drowned, frozen and shattered, being attacked by a giant cobra, all while time is standing still?

The time it'll take for the Power Animals to come down from Animarium takes longer than Eiji needs to go PuToTyra and freeze them in place, then switch to GataKiriBa and spam them with powers of his different combos :P

I don't think the Gaorangers need to get to their mecha though, since they're sentient and all. Plus there's 100 of them, so its not like they can't distract OOO long enough to form GaoKing or GaoIcarus.

My vote more reflects the fact that even though they have such a huge number of animals at their disposal, there's nothing that strikes me as particularly special about them. None of them are highly skilled, their weapons aren't all that good apart from that one combo and they get kicked around a hell of a lot in their series. If my memory serves me right they only won in the last episode because all 100 animals showed up to help them last minute.

So, one of the most powerful Riders ever vs. an unremarkable Sentai team? It's a no brainer for me, OOO.

Was GaoRanger unremarkable? Was it one of those seasons where PR direct translated? Cause I remember Wild Force being kind of meh to. Always thought it was just a cluster (Ahem) of random Zords.

Well, I have to admit I'm not being completely fair since my only experience with Gaoranger comes from Gokaiger and stock footage from Wild Force. That being said, I don't feel that I'm wrong based on these half-assed discernings. Though if someone is can prove me otherwise, feel free.

According to Linkara's HoPR, WF was a close (But not direct, due to clashing writers) adaptation.
Even so, OOO would whoop their asses :p

Also, KamenRiderOOO (The user), this is just a suggestion, but you may want to consider usin the PR teams as opposed to Sentai. You must remember that a ridiculous amount of Sentai haven't been fully subbed, pre-Magiranger...

The only problem I have with Gao/WF is the same problem I have with Dino Thunder/Abaranger. Auxillary Zords/Mechs. I mean, how many animals did Gao have? Close to, or exactly, one hundred?! That's to many. And Samurai/Shinken does the same thing. Though atleast they limited the number and made them combine somehow.
I like when there's two or three Mechs/Megazords and they combine into one monster of a thing. Like the original Megazord.

I went over the list of match-ups with OOO before this started, and I don't think there's a matchup pre-Magiranger anyway.

There is bud, 7 of them are Pre-Magiranger :/

There were? o.o -rereads list, now feels like a doof-
