Generally speaking, you should choose the newest stable release (13.10 Saucy Salamander as of March 2014). This will have the most features and best driver support. Sometimes, if in a corporate setting, you may want to use the Long Term Support version, which will receive bug fixes and security updates longer than a normal release. As of March 2014, the latest Long Term Support version is 12.04 Precise Pangolin (supported on desktop until April 2017). LTS versions generally have fewer bugs after point releases are made, but will not have the newest software ported to it when it gets older.
Note that some people may choose older releases as well, for various reasons. Using an older release is acceptable, as long as you receive any security updates that are released.
