I would try the following. Envision success at both places, what would that look like 3 years from now? What would the job duties include? What is the likelihood of promotion? What current skills would have grown significantly? What skills would have atrophied through lack of use and challenge? What new skills would you have acquired? Who would you know? Project out the differences in income and expenses and calculate an expected net worth at that point?

Now imagine the logical next steps, see yourself switching companies and taking a new job. Or, starting a new venture of your own if that is your dream? Which of those next step outcomes is more attractive to you?

My own take is that the corporate role will lead to more specialization, has better income, benefits and security over the next 10 years. By contrast, the SAAS service company will expose you to a much wider range of responsibilities. You will be more rounded. If you have your heart set on building your own company someday, this role will likely be better preparation.
