I am now using ClassicPress on my site.
I wanted a clean install so, ran it along side my existing WordPress installation and then moved things over.
I found alternatives to few plugins that I was using, and there is a away to migrate, in order to keep most of the plugins or themes that are not directly compatible.
I did find that ClassicPress had smaller file and database sizes and this was my main reason to switch over, below is a comparison chart.
