Arduino UNO is well known to be the most popular Arduino board, we agreed. There are a few reasons why Arduino UNO is so popular:
It evolve from the first Arduino board, which has been around since 2004
It is matured as many has contributed to the ecosystem, the library, the examples
There are tones of project using Arduino UNO as controller
Shields are designed base on Arduino UNO mechanically, electronic and libraries.

You will need to download the CH340 driver from here: Windows, Mac OS, Linux (pre-installed). 
 
Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP). The open-source IDE can be downloaded for free (currently support Mac OS X, Windows, and Linux).
