A bit of both. I would want startup life if I'm in a place where I could do things on my own with less supervision and be adventurous and ambitious. But I'd prefer to be in a corporate (established) ecosystem if I'm starting from scratch and would want massive peer support to grow. The latter is only because corporate lifestyle is a bit laid back and there's no you gotta run everyday pressure. So there's more stability and people have more time to help and nourish you.
P.S. I don't mean that you can't get that in a startup ecosystem. But given the records, it's more likely in corporates than startups.
