Much like the other PHP-based CMS’, Sphido stands out for certain unique features that make it worthwhile on certain projects. WordPress is great for blogs & portfolios, Magento is great for eCommerce.
Sphido is great for speed and efficiency. It’s a lightning-fast CMS based on a flat file database structure.
Naturally this is not going to be the best solution for every single project. Sphido is such a small release with a small community that it’s going to be difficult justifying it consistently. But the flat file structure allows for an easier setup and maintenance.
The CMS can be installed at a break-neck speed but it’s the config, theming, and structuring that takes more effort.
If you don’t have time to learn a new CMS engine then Sphido will not appeal to you. But if you like to tinker with new stuff then why not give it a shot?
