Quite the pickle.
1. How good are you at networking/making connections?
2. Is the DO school known to be supportive toward students?
3. Are either school P/F?
If you're good at one, the school is supportive and won't dismiss willy nilly, I'd learn towards the full ride. Having little to no debt makes a huge difference, esp. when it comes to choosing specialty, and you can make up for being a DO by networking if you want a more competitive specialty. P/F also makes a huge difference imo. It's much easier and less stress.
But tbh, we can't truly say w/o knowing more info. CoL, family/social support, etc. can also play a factor. Also, depending on what specialty you want, you may have to take STEP too.
