Choose Google. If the startup can only offer you 1/3 the pay, we can infer that their equity isn't worth very much, or investors would have given them more money. So you believe in the startup. That's great. It's great to believe in writing good software. It's wrong that someone would want to exploit that for their own gain. It very strongly sounds like what you're being offered is a pittance. Don't sell your dreams for that little, because someone that will offer you so little for your dreams isn't worth working for.
