Roosters: Yay or Nay

I’m going to be place my order for my first flock soon and to avoid an addition 35 for a “small order” I need to add three birds. I’m toying around with the idea of one of the being a rooster. Barring the fact that they are louder then hens I don’t see what there down fall is? Iv heard they can be great for flock protection but those against them are REALLY adamant they are useless unless you plan on breeding. Wanted to know how people felt about them. First hand experience preferred when responding by not required.
