Suffusion has a very large number of options, which take a while to understand, but once you have done that, it's worth it! Great front page Magazine layout, Featured posts (I use for urgent "Stop Press" type posts) it has the flexibility to work as a great CMS.
I find the "responsive option" for mobile is a good fit, which supports mobile/tablet users without the mobile needs getting in the way of good pages and layouts for bigger screens.
The support is good and updates are out regularly to track WordPress updates. This is important and (so far) I have never had a problem with the theme, (only with a couple of plugin updates - nothing to do with the theme - incompatible with WP updates!)
So thanks to Sayontan Sinha for the tremedous theme and ongoing updates. I am very pleased that I chose Suffusion for my web site!
