It´s a pretty easy way to get protein in, but it´s mostly useful for post workout.
If you take it as meal replacement, i would prefer something less impactful on your insulin level. It´s something you might want for post-workout for quick refueling and metabolizing of the protein/amino acids, but it´s not something you really want throughout the day.
A multicomponent protein powder is better, though to be fair, i do not see a point in it if you are not working out, unless you are only about maintenance and can do that with training once or twice.
