Manjaro

What do you like best?

Customizability and compatibility. Manjaro is an awesome flavor of Linux that makes a lot of things really simple (current Windows users will feel more comfortable using the XFCE desktop). There are a plethora of software options that you can make use of, and they're all free (in most cases, that is)!

What do you dislike?

It can be a little tough for new users to get used to, since a lot of things require more configuration than a user might be used to in a more mainstream OS.

Recommendations to others considering the product:

You may find some online guides on how to get started very helpful! Nowadays, Linux has gotten a ton more user-friendly than it's been in the past, so don't be afraid to explore!

What problems are you solving with the product? What benefits have you realized?

Manjaro works awesome for personal, educational or business use. There are tons of free and open source alternatives to many Windows-only programs that someone might use, and when you can't find an alternative, much of the time, you can use a compatibility layer to run said "Windows-only" apps.
