Windows 7: The Ultimate Gaming mouse

Hi guys just want to get a few opinions on the ultimate Gaming mouse.
I been looking into getting either the Razor Ouroboros Razer Ouroboros - Ambidextrous Gaming Mouse | Razer Online Store

or the Cyborg M.M.O Cyborg M.M.O. 7 Gaming Mouse or the Rat 9

But before i commit to buy (leaning towards the Razor) I would like to know what you all think and do you have any more suggestions.

Thanks Daniel

Which one you should get really depends on what kind of games you're gonna play, so if you don't mind could you tell us?

Mainly the shoot em ups i have all the COD's, Battlefield, Halo and so on.
Mass effect, Diablo will be getting Medal of Honor war fighter.
Also play a lot of Racing game's but mostly with my Xbox controller as well as a lot of the super hero games Batman, Spider man thing's like that.
So really I'm a all round Gamer and will pretty much try my hand at any thing.

Would just like a really out of this world mouse that extremely comfortable and does a all round yet fast job while gaming.

I pretty much play the same games you play and I am using a Microsoft sidewinder x8. I find it quite good
