Unlike Ubuntu, Manjaro is based on ArchLinux hence it is a rolling release (Which means you'll always get the latest software without requiring to change edition) it beats LTS.
It also comes with it's own GUI package manager and it's all up to date and free

You can also easily change the kernel using GUI to suit your hardware (not everyone is CLI whore you know)
Personally I think manjaro will get more popular than ubuntu in the coming years.
