   More flexible, can add an additional layer of security on top of your codes, lets you organize your codes into categories, doesn't depend on Google for cloud backups, and it's easy to import from Google Auth.

   Of course can you use KeePass and apps that utilize kdbx files as a TOTP generator. Just read it up.

    Keepass2Android supports TOTP. The better thing is, TOTP seed works with desktop applications too. Therefore, you need only one database for desktop and mobile devices. Also, built-in Keepass keyboard allows autofill all inputs from one place, you don't need to switch between applications.
