Know what?

Fourze > Birth > Den-O

Decade is one of the Best Riders

Tensou Sentai Goseiger is Better than Gokaiger

And Fourze will win this battle.

Come at me, people! I ain't afraid of you! Kickback maybe, but not you!

This is going to be confusing but hang with me.

Fourze is more powerful than Den-O because of a few key weaknesses in the Den-O Rider. Ryotaru being the main obsticle. He's cute, but he's weak. Physically to. Yes he learns, way later on, but for the most part he's useless without an Imagin. And that brings us to the Imagin. Here's your hypothetical.

Den-O travels to the Rabbit Hatch and, through mistakes, gets into a fight with Fourze. Fourze switches the Astro where he access to all forty switches. Den-O starts with Sword Form. But, wait, whats this? He suddenly changes to Rod form because the Imagin are fighting and bickering.

Switch Magnet
Switch Eleki
Switch Rocket

Magenet draws the bickering Den-O in, Eleki strikes his belt frying the controls, and a quick blast from rocket sends him flying.

Limit Break

And Den-O plummets to Earth.

...So what happens to Birth?

If Sentai says that happens, I'd expect Goto to have been taken out of the battle by Date to get some oden :lol

Fourze, after watching Den-O do his Shepard impression into Earth's Atmosphere, is knocked forward by punch. Turning he sees Birth holding one of his switches. Stolen from his belt. Birth tries again, Fourze blocks with Sheild and activates magnet. The switch returns, plugs back in, and Fourze switches to Fire States.

Birth tries again, he's encased in foam, while Fourze watches girls from the high school paint Birth's helmet pink. A fitting punishment for being useless as a Rider.

No. He's not.
He's strong, but no. He's nowhere near "Best."

...Yeah, sure. Fine.

Yes, yes he is.

And darn right fine. -huff-

I gave you the Gosei is better than Gokai.
But...Nah. Not the time or place.

Thing is dude, the "Way later on" still counts. If you look back, I was arguing the hell out of that point when Kiva was taking on Kuuga and W. Someone made the comment Wataru would go soak in his bath tub(Switchblade was it?) and I brought up examples of showing Wataru had matured out of that. I'm not arguing that Den-O is stronger than Fourze because if you check the results and my post you'll see I voted for Fourze. The point I'm trying to make is that people should focus on the Rider at the end of the series, not anecdotes of how they used to be before their journey concluded.

and with that I'm done speaking on the matter. Onto the next battle!

I went for Fourze again for the same reason I went for him last time.
