It’s always a good time to switch to Linux. Some distributions are super easy to learn, while others require some minor knowledge to really get off the ground. Here are a few of my recommendations.
Linux Mint - https://linuxmint.com/
Ubuntu - https://www.ubuntu.com
Debian - https://www.debian.org/
Fedora - https://fedoraproject.org/
I personally use Debian. It is my favorite of the bunch mentioned. It requires some configuration for me to get up to where I need it, but it runs flawlessly once I’m there.
Linux Mint is really good for users switching for the first time. It is also my recommendation for new Linux users. Its default look and feel is akin to Windows and users will feel right at home out of the box.
Ubuntu is similar in usability to Mint, but Canonical isn’t great and has made some very poor decisions in the past. Doesn’t have a Windows like interface by default, but is really hard to break if I remember correctly (I haven’t used Ubuntu in probably 8+ years so take all this with some salt)
Fedora I have the least experience with. It seems to be a hit or miss distribution, but some may find their home here. Also ships with an interface that windows users would need time to adjust to.
