Face it, we're talking about your "main OS"

Everyone knows dual-booting sucks anyway.
Windows is for wimps.
MacOS is for mental midgets.

Therefore

This article is, by necessity,

DEATHLY SERIOUS.

We have three new entrants, ready for a nice hazing. So here goes:

SolusOS

strengths

• Gorgeous budgie desktop environment
• Budgie has great gtk compatibility
• It's own package manager

weaknesses

• Very few packages available in the package manager
• This is a desktop only os, not suited for servers
• Small dev team and community limits project velocity

Gentoo

strengths

*Package manager builds things from source

• ULTIMATE CONTROL
• EVERYONE WILL KNOW YOUR NECKBEARD POWERS

Weaknesses

• No one can come up with a scenario where it is better than Ubuntu, debian, or arch, especially since it's package manager doesn't pull from project git repositories. It will remain a polka dotted horse in a field of Jersey cows and wily werewolves and the like.
  • Unless that scenario involves things that people pay no mind to.
• Just you try for enterprise adoption, just you try....

SuSe

Strengths

• Gnome and KDE support!
• It's French!
• Yay now we can use redhat packages....
• Provides the Linux community with a very handy automated packaging tool. Really it is great.

weaknesses

• It's French!
• Only really supports KDE
• Uses redhat packages
