No infix operators is an advantage. I don't like memorizing precedence tables; most of the time people use parens just to be on safe-side anyways. It's even considered good practice in most cases. I can see how lots of parentheses can look irritating (particularly at the end of expressions). But once you are familiar with it(it's not that hard) you can just read between parens and you don't see them anymore(most lisp code is well-indented). There is also a thing called sweet-exp that is supported by some popular lisps.
