I've been using Bluestar Linux for two years now and I really like it. I found it at SourceForge because it was featured there that week. It was quite a new experience for me because I was used to having an Ubuntu-based Linux OS. Pinguy OS was the previous one that I used.
I haven't regret making the switch to an Arch Linux based OS. Once you installed it, you can keep it on your computer because the new Linux kernels can be upgraded through their package manager PacMan, and that way you have an up-to-date operating system.
I like Bluestar Linux because it contains quite a lot of software but not too much.
The support is excellent. If you have a problem with the installation or anything else, you can easily contact the developer via the Facebook page of Bluestar, or through his email address.
I recently had to reinstall Bluestar because of an Arch Linux bug having to do with attaching external drives, or it could have been caused by a corrupt installation. And thus I installed the latest 4.11-3 version. It's only a 1.8 GB download. When installing you can choose to install Base, Lite, Desktop, DeskPro or the Developer version. It's recommended to put the ISO onto a flash drive so you don't run into problems when you install it from a burned DVD. The developer is even trying to improve this, he told me.
Previously Cairo-Dock was installed but because that's no longer being maintained by their developer, Bluestar now comes with Latte Dock which also gives ya a MacOS look and feel. If you like this too, try out this awesome Linux OS ! You won't regret it.
