CDs are pretty useless. you can get the same quality digitally now.
Vinyls at least have the collecting factor, because of their size they are great for displaying the Cover Art, and many release special editions with colored Vinyls and stuff like that. while CDs are rarely as nicely made. some DigiPacks are still kinda cool, but even those are usually not as cool as Vinyls
the only CD albums I would still buy are ones like these ones, which are really nicely made:
these in particular also are about the size of a Vinyl cover, so the art is nicely displayed
