I agree with Michael Brady et al. (subscription required, but adequately excerpted below):
I loathe Arial. I think it’s a crappy variant of Helvetica, flying just below the radar surveillance of the copyright-infringement patrol. I get involuntary glottal stoppages when I see the terminals of the round letters, the doofus dormer at the top of the lowercase t, and other infelicities.
So I am amazed that I have fallen in love with Arial Rounded. I do
like the face, her alluring curves, the seductive way her parts join
together […]She’s also a very legible typeface under awkward conditions. Stuff like telephone pole signage that has to be read from passing cars works very well in Arial Rounded….
