I chose multiple summer internships over a year in industry and used the year I saved (from not doing the year in industry) to do my masters and I also have worked in 2 part time internships relevant to my degree boosting me to more experience than I would have from just the year in industry as well as having the time to take an MSc, I felt this was better for me ut there are loads of advantages to doing the full year out too, like you would be able to get more settled and maybe get chance to work on a variety of projects or take on more responsibility.
