So far, impressed.
Been an avid evernote user since 2006. Have always wanted to use the service as an integrated productivity/task solution but the mobile app requires way to many taps to sort lists. The newest version of the evernote mobile ios app, which is a radical re-write, is nice, but still emphasizes note creation over note interaction. Clever provides a simplified layout that gives direct access to tags, notebooks & saved searches from the menu bar. Not all of the options in a messy list, bit the ones you choose. This allows me to have more control over the experience and not give my folders weird names (with a "!" or "*" in front) to make that folder or tag rise to top of the list. Still putting it through its paces but I see lots of potential.
