If you go to SoftCo it might be a chance to improve an existing product niche like Flemlord suggests. But if you try a startup (30's a lot & I'd call this big) you might just see how hard you really have to work and learn something new as well. If it was me I'd pick the one that gives you the "best payoff" for working up-wind in the future.
