You make one stare to a corner and you go. Circle makes you constantly keep your neck turned.
Not my thing.
I’m not in St. Paul, either.
Your neck don't constantly turn. You still look straight ahead as you turn with the circle. That would be dangerous if you keep your neck turn in a roundabout. It's like going on a straight road and keeping your head turn to the side.
You haven't try one but once you try it, you'll see what I mean. It doesn't have to be your thing as sometimes you may just approach it since there are also many roundabouts in the U.S. too.
I'm sure ProudLao would agree about the turn head thing too if he drove through the one next to the soccer field.
If you're in the Twin-Cities, there are several roundabouts in that area as well as other areas in the state of MN.
After doing both and you still prefer square, nothing wrong with that either..
