Generally speaking the results I've seen so far indicate that at low bitrates (e.g. below 0.5 bpp), the video codecs (AVIF, HEIC, VVC) perform best, while at medium to high bitrates, JPEG XL performs best. This makes sense considering that video codecs aim at lower bitrates than still image codecs. Basically video codecs have more coding tools to "hide artifacts" at low bitrates (e.g. strong smoothing filters), while JPEG XL has more coding tools to "preserve detail" at high bitrates (e.g. strong entropy coding, more subtle filters).
