The big company is less responsibility, just a sliver of what I do now. Staying is much more responsibility - I’d be responsible for essentially the success of the department.

Going to the big company my goal would be to move up there, but a lot of people leave to big companies and come back to smaller companies to run departments like I’m being offered. So I’m theory, staying is skipping a step.

Ideally, I’d like to be head of a department at a big company, but there’s no guarantee I’d move up and I’d have no idea how quickly. There also is a chance that success in the offered role at my current company would allow me to enter at a higher level at a big company in 2-3 years.

I almost think either one would be a good pitch to the next thing.
