It is her second/third best album. And before Madonna stans attack me, I'm not saying it's not R&B (that's arguable though). It's just not as amazing as the other albums you listed.
I think it is though It's not as influential as those albums, or considered a "landmark" but that's for many different reasons (the main one being that Madonna isn't primarily a R&B artist). I think it's a 10/10 though.
