I am of the sharp corner camp. I like it boxy. That is sort of how it was with all the Notes historically, and while I don't hate the rounded corners - I just held onto my old S8+ and I could not get used to the rounded corners again.
Also, now when I look at the camera punchout vs the S10+ punchout, the S10+ punchout looks humongous. I also like the center placement of it too.
