Comparing a font using all caps with a font using lowercase isn't a fair comparison, we know that all caps is harder to read (source: some paper at some point as an undergrad when I had no bibliographic database - and my own experience). I agree with the comments that see no real benefit to the rounded corners except for the one comment I read that points out that we see sharper corners as more fragile. I think there may be some sunk-cost bias here - if you spent a lot of time and energy making rounded corners at a time when CSS didn't make it easy, now you'll have quite a bit of cognitive dissonance concluding that rounded corners are no better than sharp ones.
