If you aren’t a working professional on a tight timeline, I’d take the time to do a thesis! Only saying this because of the people I know who did a thesis, they all seemed to run into obstacles that delayed the process a bit (lab access, slow ethics approval, etc.). I’m coming in to my program as a working professional who will be working full time while studying, and want to work in a more applied setting so I picked course based.
Better to leave a door open than totally shut. Especially if you think you might want to go with more education or focus on research/clinical studies for a career! Good luck with your decision!
