I've seen a lot of people who quite dislike Manjaro, and I'm not really sure why. I'm myself am not a Manjaro user, but I did use it for quite a while and enjoyed my experienced, as it felt almost ready out of the box. I'm not here to judge, just wanted to hear the opinion of the community on the matter. Thanks!
I see some people say Manjaro has no place--to just use Arch or some other easier to use distro. IMO the more linux distros the better. I think many believe that more distros means its harder to get support, but using linux is also about being resourceful, and many things other distro communities have solved can be utilized in other distros.
Innovations that Manjaro makes can have an impact on their upstream, and the linux community as a whole. It fills a niche that might get someone to use linux that otherwise wouldn't. At the end of the day what helps out all of the linux community is the number of users.
