Just because Gaganade a Jazz album with Tony Bennet that doesnt mean it will instantly get high scores. Yeah its different for Gaga but generally I dont enjoy this album
The album features Streisand singing duets with an all-male lineup including John Legend, Michael Bublé, Andrea Bocelli, Billy Joel, Lionel Richie, Stevie Wonder, and Elvis Presley.
Babs' album is vocal pop, not jazz. She'll submit in traditional pop vocal while Tony and Gaga will submit in jazz. Also, Barbra hasn't won a Grammy since 1986 (not including hall of fame inductions) so it's not like she's exactly a consistent winner. Though the duets might play to her advantage.
