Yup. Pretty much the only info you need to decide this one. Accel.

WRONG.
You're including information you know later on (Notably, ANYTHING about Soukichi. New viewers will know nothing of this man other than he died). What we see is monster shooting blasts, a guy in a white hat get killed and give his hat to some other guy, an explosion, and a transformation.
You have to remain impartial. It was a cool opening, but only served to introduce Shotaro and Philip. I found Anything Goes to be a much better theme than WBX, and the rest of the episode is just par for the course.

It's Kamen Rider. And T-Rex's and Magma's designs weren't anything special to me.

Like I said, that opening was good, but you're giving it way too much credit.

Yo, Hibiki, I'm real happy for ya, Imma let you finish but

AAAAAAAAAAAAAA-MAAAAAAAAAAAAAAA-ZOOOOOOOOOOOOOONNNN!!!!!!

shin for his sub zero fatality

"A neon forest green, red, and white dragonfly on a motorcycle" to be exact :)

Oh, and I vote Accel.
