Someone just starting out with Linux might want to try something easier to get an easier experience. Someone who likes to dabble with different software and OS's will be better prepared for the differences.
I haven't tried the others, but based on what I have read, Manjaro was the only Arch distro I wanted to even attempt. No regrets. Low system resources, good repository and you always have AUR if you want, too. Seems really fast, and highly configurable if you want to get your hands dirty.
