There is nothing “wrong” with Arial and Helvetica Neue. They are just common fonts, and some designers look down on them for being “overused”. Really though, the average consumer wont care at all. Content is king, and those fonts look good. So it doesn’t matter. It’s just designers who get nitpicky over them.
Same with comic sans really. The font isn’t so “bad”, it was just used a lot, and used inappropriately. (gravestones, etc.)
