So why did you just happen to pick one of the largest with lots of manpower, large repos, lots of software support etc and not for example RebeccaBlackOS (yes, that exists and no it is not what you think)?
There has been quite a bit of standardization and improved compatibility, so that you can choose relatively freely between the "big" distros. But that does not say they are a commodity but rather that all (five or so) of them are good.
People tend to go for the big names everyone has heard of because they're the big names everyone has heard of. A no-name distro is probably fine too though.
