Having already been there once, my goal was to check out what it would be like to run the install as a newbie and focus on getting my eMachines up and running, rather on checking on the performance which has been well documented for Mepis and Ubuntu alike.

Overall I will have to put this pretty clear, as I know there are a ton of Mepis lovers out there who are probably ready to bash my lack of Pennies, however there is a reason: Mepis is rock solid, works well, and offers a true desktop Linux, BUT really is not that unique. To me, this is like someone who like a Mercury over a Ford. The chasis is the same, only the packaging is different. For Mepis, this is true with Kubuntu. I am a big fan of Kubuntu and equally a big fan of Mepis. They both offer what anyone would want and that is a distro that works and works well.
