The "R", "r", and "t" characters are the way you can tell between the two fonts.
I think an example of a bad logo is Arial is this one:

The A has too much space around it and it looks "uneven".
The bottom one of this one is Helvetica.

It looks "fuller", "denser" to me. And leaves me with an impression of a "sturdy" company.
Finally, here's Neue Helvetica 75 and Arial Pro Bold pages from Linotype. I just open them up in a new tab each and switch tabs to get a better idea for things.

I’m not sure I see a huge quality difference in the second example, but the A in the first example definitely looks awful.
I guess it would fit your point a little more if I just looked for whichever I thought was more aesthetically pleasing.
Anyway, I got about 50% (accidentally closed the window, I think it may have been 51%?) so at least if I was the customer, the company would not seem to gain any advantage from licensing the superior font.
