I also switched from A+ to Roon a couple of years ago for the same reasons. Last year I bought the lifetime subscription to Roon, I was so convinced about its superior SQ, compared with A+.
However A+ 3.5 has changed everything on my setup. It sounds better than Roon. I use Roon these days mainly for its wonderful radio, connected to Tidal. And yes, the GUI is great. But on those occasions when I really want to listen to my music, I go A+ 3.5. For me, the difference is component level - using no filters or upsampling on either.
