Some favorites in the order I discovered them:
Settled (for now) with ypn envypn because it’s a bit more spacious than Cozette, and it scales better. Cozette is pretty good looking, though.
There’s something about monospaced fonts that makes it addictive. All other fonts seem like a bit too much after a while.
And then there are bitmap fonts; after you get used to them, everything else seems blurry.
