OP, this is terrible advice. Do not follow! Unless you run into a problem with Ubuntu LTS or distro based on it that you and the community cannot solve and it’s due to the LTS, stick with LTS. The vast majority of users are on LTS which is why there are tested solutions for most common problems you might run into. LTS releases last for many years so once you solve a problem, it’s likely you won’t have to solve it again for a long time, unless you decide to make your life more interesting by upgrading or changing the OS. Non-LTS releases last for 9 months or so, then you’re thrust onto a new set of changes and bugs that may or may not hit you, with much fewer comrades to test them and find solutions for. As a new user, if you’re going with Ubuntu or Ubuntu-based OS, stick to LTS. You’ll have enough hurdles to cross getting acquainted with the OS itself.
