Correct bracketing would be plenty in this case. If-statements sometimes (not always) make code much less readable than ternary operations.

This is why more languages should adopt the every-form-returns-a-value paradigm.

Sometimes, if-statements unnecessarily add lines, and the lines become harder to read.

I would say it's a case-by-case statement. Well, okay, more specifically, I would say that the use of a single ternary if is a case-by-case statement.

Absolutely. I use ternary if when appropriate. But nesting ternary ifs is horrible, and nesting ternary ifs while discarding parentheses is malevolent.
