It's kinda hard to evaluate the fonts when only fully capitalised samples are used. COBOL went out with Clement Atlee - we kinder, gentler Rubyist types like our lower case code.
I second the lower case, being a Linux user type. I was also expecting more analysis in this post than just whether the zeros were slashed or not. adg below posted a link to a former and similar article that I think has that analysis I was looking for.
