Your assistant already has a favorite. Of course it does. It has been optimizing a story you fed it for an hour.
A mentor has seen people take both kinds of job. They do not have your spreadsheet. They have pattern recognition you cannot rent from a model.
Ask for an opinion
Opinion, not a decision. After they answer, you still sign. If you ask "which should I take," a kind person will pick so you can stop spinning. That is not what you needed.
Ask: which of these two constraints would you not bet a year on? Or: where is the frame wrong?
Separate the offer from the story
Facts: title, cash, equity as written, location, start, the date the offer dies. Story: "this is the stepping stone to X," "the team is kind," "I will not have to travel." Mark the story as yours or as inferred. Your assistant has opinions that read like facts.
Respect the inbox
They did not book a call. A busy expert can answer from a phone. One page. One question. A deadline that is real because the offer has one.
If they have no account, the mail is enough. If they want a call after they read it, you both arrive already knowing the numbers.
