The difference on consoles (And PC)

I just want to say before I get into this, this is from my experiences on each console (And PC).

So. over the years of playing on console and PC, I have seen many different communities, now, the first I've noticed, is that Xbox 360 and One have way more kids than Ps3 and Ps4, and especially PC. It's hard to find any game on there that a kid isn't on (Maybe even impossible). In the beginning, it wasn't so bad, but after a couple years, the kids flooded on. As for Ps3 and Ps4, there are a lot more mature gamers and adults, I only owned a Ps3 for a year, then got rid of it, but while I owned it, I only encounter 1 or 2 kids on my games maybe 1-3 times a month, and, there wasn't as many ragers or people blasting music (For the most part). Now, onto the PC community in gaming, there are pretty much no kids on here, mostly because no kid's gonna have a PC that can run the games most normal gamers will play. But, it's not a utopia, alot of the people on are teens and adults, and sometimes, some of the Guys would have their mic plugged in, and they'd be screaming when they lose (Mostly because they play the game like it's their lives). So, I wanted your guys' opinions. Which is you preferred or best community in gaming, Xbox, Playstation, or PC?
