Canon Or Nikon?

Some says....Of course Nikon la
Some says....Canon is better

I'm confused~~~~

So...I'm stuck at a tie of Canon 550D and Nikon D90
I personally prefer Canon actually
But i have to make sure i don't regret after buying
Its not buying few dollars stuff...its few k
Canon 550D won't have stock til the end of this month...
I have time to decide
And yet...choices are always confusing
Agree??

Canon 500D VS. Nikon D90
Round 1 fight~~~

(=.=...okok...too much of street fighter games when i was a kid)
