I'm not a developer, I'm an engineer, but I think the same principles apply. If you want to become the best at what you do, you must surround yourself with people smarter, more experienced, and more capable than you. So, go to the company from whom you can learn the most. If a particular startup has an experienced / innovative team, go there. If you find the same thing at a corporate giant, go there. I started my career at a startup, but found I quickly exhausted their expertise since their team was 'limited' in experience, capability, etc. So I ended up at a Fortune 500 where there were thousands of engineers to learn from. In the developer world, it might be completely opposite - the good ones are at startups. Just as employers pick their employees carefully, you should pick your employer carefully :)
