Can someone advice me about the 'best' distribution?
If it didn't happen so often it's sad, I'd swear this question was meant to be a joke. If there was a "best" distro, we'd all be using it. Check out DistroWatch.com ... any of the leading distributions will be fine. If you think the support available with a "for-pay" distro is desireable, check out Xandros, Linspire, or the enterprise versions of Redhat, or Suse.
Edit: Another "Which Distro" thread in the LFS forum. Maybe there should be a big sign there that says "This Ain't the Place"
