Baby Miller 6th vs 7th Editions

MS3 here. Doing my first elective in anesthesia and really enjoying it so far. As I'm thinking about away rotations and learning more about anesthesia in general, does anyone have insights as to whether the 7th edition of Baby Miller is worth getting? Or if the 6th is enough? Thanks.
