On: So you think you can tell Arial from Helvetica?

[onion2k]

I scored the same, for the same reason. What I find interesting is that the Helvetica logos are a lot nicer in my opinion even though the difference is subtle. Having things parallel to the baseline improves the look dramatically over the angled bits in Arial.

Same score. I also applied the same heuristic. I wonder what I should have looked for in the MATTEL one.

It's very subtle and more pronounced in the other logos shown, but the horizontal line in the "A" is closer to the baseline in Helvetica than in Arial.

[chrisWhite → simongr3dal]

This probably is more to do with recreating the logo imperfectly than the font itself but the kernning was way off on the Arial version.

Exactly what I used for reference to decide as well (got 20/20).
