I find them a touch easier to run (equipping and utilizing Savant tricks can be a bit cumbersome). Personally, I feel like the Savant is a bard without magic (especially the Vox); Scholar is a bit harder to draw a direct comparison to another class.
I was going to say (Morrus beat me to it) that Trials and Treasures has you covered for what you're looking for. The 3rd party book Stranger Sights (for A5e) has even more.
