I think the early rounds of those trying to get people to switch to the format were motivated by the fact that tapes were easily recordable by everyone.
Tapes tear and require mechanical parts. But it wouldn’t happen were there not commercial interest.
Tapes are overall simply worse. The fact that the more you use them lends to them becoming worse quality overtime is a big reason they suck.
The CD wasn’t really suited to be played Mobile (though I did have a portable CD player). It should rather be compared to vinyl in that regard.
I think tapes are great because no portable audio player ever came close to the Walkman regarding its cultural impact. The fact that anyone could record tapes opened up a lot of creative options.
For properly mastered music to be enjoyed at home on a potentially expensive setup, the CD was very close to perfect.
If we are talking portables, then just get a simple mp3 player and rip the CDs.
Except cds had better audio quality, you could shuffle or skip, they didn’t where out or get “eaten” by the player, there was no rewinding or having to flip the tapes over, you could install cd changers in your car so you wouldnt have to swap discs around, and there was still no preventing you from recording a cd onto a cassette if you wanted. My old boombox could bootleg that shit easy as could be.
No one in or out of the industry wanted to keep cassettes. By comparison, they were trash.
