Dark Is Card

What is the better card, Dark Armed Dragon or Rainbow Dragon?

I meant Armed Dragon lvl 7
Also, Dark is banned.
By the way, this is just for fun, like a poll. I actually prefer Rainbow Dragon because I have a crystal beast deck! Dark Armed Dragon is banned now so all you guys who voted for that, you're wrong. Anyways, I meant to poll on Armed Dragon Lv. 7 and Rainbow Dragon.
Does anyone else run a crystal beast deck?

Duh... Rainbow Dragon! It's the best Crystal Beast card!!!
