Which Linux distribution to choose for my VPS?

Although any Linux distribution can be configured for any task, the out of the box features and intended use case differs between them. Here are the differences between the main 3 distributions on offer for Veesp VPS services:

Ubuntu has the biggest market share and the largest community, which leads to readily available solutions to most common issues online. It is great for hobbyist servers, developers and simple non-mission-critial web servers.

CentOS is built to be the most robust and stable, as a free alternative to the commercial Red Hat Enterprise Linux. It often times does not have the latest versions of software available on it's official repositories. But the versions that are available are tested and deemed stable and dependable to be used in mission-critical enterprise environments.
This is by far the best and most stable distributive for web-servers, mail-servers, ftp-servers and other use cases that require long term stability.

Debian is popular among developers due to it's balance between cutting-edge software and stability, as well as it's tried and true software distribution method and a helpful community.
Debian is great for developers and hobbyists, but although setting up a web-server is as easy as on other distributions, we suggest using CentOS for this purpose due to it's robustness.

Note that this covers only server environment. Desktop (or remote desktop) use has additional/different requirements.

Comparative table:

¹Relative to each other, but a lot of the solutions for derivative distributions can be applied to each other, so this point is slightly moot.
