Due to local ordinances, many people cannot legally keep roosters. That is a sad commentary on our culture.
I lived and worked in Costa Rica where many people have chickens (and roosters) all over the country. I had to be at work quite early and loved the fact that I never needed an annoying alarm clock. Instead, awakening to the gently rising crescendo of area roosters waking the world. In fact, everyone there is up and working shortly after dawn. I'm sure this is the case everywhere that people and chickens work from dawn to dusk.
Roosters aren't as loud as trains, dogs, lawn mowers, weed eaters, roofers, motorcycles, boom boxes, etc.. When I'm in my house, I can't hear all the roosters crowing but I can hear the train whistle 3 miles away, neighbors mowers and loud traffic
The answer to the title question depends on one's personal circumstances and goals.
If one has secure run and coop for a handful of chickens, there really isn't a need for a rooster.
I have anywhere between 3 and 7 flocks from time to time with at least one rooster running with each free range flock. I almost never have less than 5 roosters (current). But there are times I have 10-20 roosters, some in bachelor pads.
The reasons to keep roos are as follows:
1. Flock alarm and protection
2.fertile eggs
3. Eye candy
...
I prefer bantam roos for many reasons:
1. Less space needed to keep them
2. If there in a flock with bigger hens then there's less stress from over mating
Yes there is cons with keep banties in with standered sized hens but if done right or raised together since chicks there shouldn't be an issiue.
I currently have 2 serama roos in with 29 hens I could have more in there but they do fine they love the hens less stress on the girls and the boys get some lady time

@RoostersAreAwesome I'm pretty sure has a great flcok going and could tell you about it
Roosters also find food for hens/chicks and keep watch for predators while the flock eats.
They are also good at keeping peace in a flock.
If expecting flock protection from a rooster, I wouldn't put that onus on a 2 pound bird.
I think large, agile Mediterranean roosters with the ability to fly up and take a hawk out of the air work better. While they may not be up to survive a coyote attack, they will take on the challenge giving the hens time to take cover.
Meds like Minorca, Catalana, Andalusians, White Faced Black Spanish and Black Penedesencas.
