Which one is the best out there?

I have seen F50i , Predator from adidas
and
Nike Zoom Air Total 90 II FG or Nike Zoom Air Total 90 II SG

any boots are appreciated. Please give Pros and Cons.

Personally, I prefer the Mercurial range for speed.
The F50i's from Adidas are also a speed-designed boot, where as the Nike Zoom's drift of into a more controllable area, such as for more accurate kicks.

The Zoom's also offer more support for your feet, if you have sensitive feet from running for too long.

I myself, as I prefer, have the newest Mercurials.

I Have those and they are pretty good.
Easy to play with and mine has the fiber in it with make it more accurate and light.

I have those, nee new.
