Hey zlwjoe, I also got accepted by these two programs. I decided to attend Columbia (although I've already said yes to Georgetown, still have to tell them). I also struggled between the thesis vs. internship part, but in the end I really liked Columbia's electives that I felt it fits more with what I wanted to learn. And, of course, the name shines in Asia.
I think you might want to consider Columbia. Having worked through a research thesis may help you with the R&D career, and you get a more solid science/lab learning experience.
And for R&D, you might consider a PhD in the future, then you'll definitely need a Master's thesis for that.
Hope this helps
