Ranked in these QuestionsQuestion Ranking
Pro Good legibility
Different character categories are differentiated by height and alignment. Numbers are a line width smaller than capital letters, so there is no need for a dotted or slashed zero.
Pro Four styles available
Sudo has Regular, Italic, Bold, and Bold Italic styles available.
Pro Works well on Windows
Sudo is hand-hinted for good rendering on Windows.
Con Zero is not slashed or dotted
This makes for difficulty in distinguishing similar looking characters, such as the capital "O".
