Pro Can be officially systemd-free
Gentoo's default init system is OpenRC. Gentoo also officially supports systemd-free Gnome and udev. Users are free to choose any init system they want.
Pro Great for anyone who is serious about learning the intricacies of Linux
It's useful for both beginners and professionals. For the installation, Gentoo offers various types, which are referred to as stages. Basically meaning how in depth you would want to go into the process of installation. For beginners it's useful to choose for a starting distro due to its various stages that can be very time consuming but beneficial as you learn the composition in general of Linux.
There are many architectures available for Gentoo : i386, x86-64, PowerPC, PowerPC 64, sparc, DEC Alpha, ARM, MIPS, PA-RISC, S390, IA-64, sh, m68k.
Pro Documentation and community are second to none
Provides a whole handbook to refer to during setup and usage.
Pro A very large collection of software is available
There are more than 19.000 packages available in the official repository. And even more with overlays.
Pro Gentoo does not impose a standard look-and-feel
Pro Live USB
Pro Fully customizable
The usage of advanced features like USE flags makes it more customizable than any binary distribution.
Pro Can by optimized to any given CPU by using proper compile flags
Since everything is being built on your PC you can tune the code to make use of your CPU.
Pro Android apps
Android apps add basic offline functionality.
Pro Booting & updating
Chrome OS boots from power off in about 7 seconds. So you don't need to leave it on and consuming power when it's not in use. You NEVER download and update any apps, although the OS does update itself. Web apps live on servers, so they're always up to date and virus free.
Pro “Just a web browser”
On the other hand it’s pretty difficult to mess up “just a web browser”. You might get a few less phone calls from your elderly relatives about how they broke their fancy new email and internet machine.
Pro Full laptop form-factor
Unlike tablets, the home of most hyper user friendly operating systems, Chromebooks come on an array of devices that don’t require you to buy any flimsy keyboard attachments.
Pro Pushes oneself to use (and learn how to use) cloud based solutions
With this ChromeOS also eliminates the time needed to configure the local environment.
Con Not beginner-friendly
You have to read a lot of instructions to start, even if you are familiar with Linux.
Con Customized package installation can take a long time and cause installation failures
The Gentoo package management system allows you to configure what compilation flags packages should support - i.e. specific processor flag support (SSE, SSE2, etc.), -O1, -O2, -O3 optimization, etc.
If you accept one of the default flags, Gentoo downloads binaries from the server. However, if you decide to optimise, it can and will download all source packages and start compiling allthe programs and libraries on your system. If your chosen flags don't work with a particular library, installation will fail.
Con Has no live images with graphical interface
Full installation is hand-made with a CLI (Command-Line Interface)
Con Since everything must be compiled it takes a lot longer to update
And if you have to update the kernel or some heavy software like Chromium it can takes hours if not more on weaker hardware.
Con “Just a web browser”
There aren’t really any applications you can get on ChromeOS. If you can do it via Chrome you can do it on a Chromebook, but not much else.
Con You might need a cloud printer
If you don’t live in the paperless world yet and you haven’t bought a new printer in the last three years you may need money up for a new cloud enabled printer.
