Weird opinion: I like square brackets, angle brackets are neat, curly braces range from neat to ok.

But I just don't like the look of parentheses compared to the others. They especially look ugly and clunky when you need a bunch of them in a row, in a way that's not true for the others.

I can't think of a reason why I feel this way apart from the fact they tend to be very clunky in math too. They're also the ugliest one when handwritten despite being the arguably simplest shape.

All that said it annoys me how parentheses are the most used bracket type in programming.
