The question is not as simple as the title suggests. I am not a newbie in tech at least as per my experience. But not much experience in Linux.
The basic difference is the UI between all linux distros. So one should choose any distro just based on just the UI. What makes a distro different than the other? When every linux software works on any distribution then why is it suggested at so many places to choose Ubuntu instead of elementary OS.? Even if Ubuntu software store has more apps but those apps can still be installed on eOS. apt get install should install any package available in Ubuntu in eOS too.
Can someone explain how a distro differs from another distro. Exclude UI, stability, personal preference etc.
Mainly capability of a distro. For example how Ubuntu is more capable than say eOS or any other example. How their capabilities differ?
