I'm a huge fan. Have had surprisingly fantastic results with JXL (smaller size, same quality). Lossless option is huge bonus. Encoding tools are ready to go and work as expected (unlike AVIF, etc). I recommend XnView (there's a portable version) to check it out, convert, test, play. The format just needs recognition and adoption at this point.
