Don't go looking for it if its not that available.
Try for the S4.... its smaller, has a bigger screen, looks more stylish and feels a bit better in the hand. They'll get cheap really soon as the SGS5 comes out.

I only recommend the S4 over the Nexus 5 for its microSD and removable battery.

If possible, get the Nexus 5... its cheaper, more premium and has the best software possibilities. Perhaps you might even boot native ubuntu/linux on it? But chroot is always there.

But if only the best will do, then there isn't anything that trumps the NOTE 3. Well, maybe the iPhone 6/Nexus 6
