Ask HN: Should I intern at a Startup or a small Venture Firm?

I am planning to take next semester off and get some work experience under my belt. Now, I wanna get an opportunity to learn how startups operate, how they scale/grow, mostly wanna get some insights in the growth area. So now I am in little dilemma here, I got this internship opportunity from a small size Korean venture firm, and I am also applying to various small-size startups, and I am confused which one to go for.

So given i've 6 months, which one do you guys think is worth putting my time into? A startup or a venture firm. And just to be clear, both of them are small size and not very well known across globe.
