Go back to your earliest surviving, coherent Maxell cassettes -- in my case, home-recorded in 1977. Quickly you'll remember that what on cassette requires precisely-timed rewind, fast-forward, or tedious record-over, can now be accomplished at the touch of a remote player button.
Sound quality? As noted by OP and many others, cassette is great. Heard some obscure gems from 30-40 years ago that sounded better tonight than ever before. This old analog cassette medium is divine.
The knock on cassette is not sonics. It's hassle, outright impracticality, and, come to that, obsolescence. If you have cassettes that you still want to hear unedited, that still turn at the intended speed (Maxell, most likely), and still own a working player with working remote, then by all means incorporate the old device in your current system and use as desired or needed. Otherwise? Put all available desired content on a digital playlist, click by remote to a good DAC and beyond, and spare yourself a world of hassle.
