If you look at the Burgevouns comparison Berkley mono is the least good. It's compared to non-mono fonts which, naturally, have better kerning. Having three different representations of the number 0 including one that is indistinguishable from upper case o makes this a no-no for coding from my point of view. It's one of the first things I look for and why I love Hack.

You get to pick which kind of 0 to use. If you don't like the plain one then use a different one. It's better to have options.
