Which version to install now for easiest upgrade to 14.04 LTS in a few weeks time? I'm deploying a server and would like to use 14.04 LTS on it. The final version seems to be scheduled for release on April 17. Which version should I install to make the upgrade to final the easiest?

* Should I install 13.10 and upgrade later?
* Should I install 14.04 beta and upgrade later?
* Or should I just wait a few weeks to avoid upgrade hassles, since it's not that time critical?
