I think I'd have to go with OOO here too.

I really like a lot of them though. Fourze and Meteor's are great. Love the W sounds. Wizard's sounds are growing on me.

This right here. Faiz has the best one. The others from the other Gears are cool as variations, but I'll say that Faiz has the best.

It's my favorite, but the menacing Orga one is up there.

I'm bored. As a testement to that here's my top four.

4) Kamen Rider Decade

Fourze didn't make the list because it's a sound thread, and his isn't great. He is. But his sound not so much. Same with W. I love Cyclone Joker, but it doesn't make the top four for me.

If I'm going just by sounds, Kabuto, though that's a full package thing. All the sounds on that suit complement each other. It all sounds like a piece of tech. Meanwhile, belts like Wizard's are so disjointed when it comes down to just sound.

Now, if it's just henshin sounds, early Kuuga when he punched to henshin. I prefer the henshins that don't interrupt the action and since there's punching sounds I'm counting it.

I love how OOO is your third ^_^ (3 motif lol)

Was wondering if anyone would catch that xD
