Ask HN: Working at a startup vs. working at an established company?

I just wanted to re-ignite this discussion now that we're coming off of a high in the startup ecosystem. It'll be interesting to see how people's opinions have changed over the past couple of years.

Personally, I've seen the fervor cool down considerably and I see a lot of peers gravitating towards the more established companies. Even in the public tech markets a lot of the money is seemingly going to the FB/Goog/AMZNs of the world.
