Anonymous Pro is easily legible at small sizes as a bitmap font.

Characters that could be mistaken for one another (O, 0, I, l, 1, etc.) have distinct shapes to make them easier to tell apart in the context of source code.
Pro Looks great even without anti-aliasing
Many fonts look terrible without anti-aliasing. Not Terminus, it looks clear and crisp.

Pro Beautiful crunch pixels
Pro Pixel-perfect rendering
No blurry characters ever. Every pixel on the screen is used to its full capacity.
Pro Terminus is not going fat
Many fonts are fatty when they are used relatively large in size but Terminus does not have this issue. And now it works with IDEA.
Cons
Con Small 'l' (ell) is too similar to big 'I' (Eye)
You can tell the difference but need to concentrate on the letters.
See the word "Illegal" as an example.
It would be better if serifs are a little bit wider for the big 'I' (Eye) letter.
Con Smaller than other monospace fonts
Con Small punctuation makes readability difficult
In some programs it's hard to see punctuation marks, especially periods and colons.
Con Smaller then other monospaced fonts
Size 13 of Source Code Pro is slightly larger then size 14 of Anonymous Pro.
Con "0" glitch
The 0 (zero) symbol has a 'dent' on the left.
Con Exaggerated italics
The italicized version of the font is too slanted, meaning that italicized comments in code look really unbalanced.
Con Hard to distinguish [ and {
Braces [] and {} are very similar.

Con Italics are not very appealing
Italicized Terminus TTF doesn't appear as aesthetically pleasing as it was intended.
Con It doesn't look very nice
Con Square
Con Easy to be confused with different brands of the same or similar name
Like Terminus (Russian production company), Terminus (terminal emulator) or Termius (SSH client).
