So A is giving you 7k more money after healthcare and signing bonus for the first year, and 17k more for subsequent years. B gives you a one time 20k (dollars?) worth of stock options.

I would take the cash, how many years do you want to stay at the next place? The math is pretty easy.

I personally choose based on who I want to work with, how I think I’ll grow professionally and is the company doing something I want to be involved in.
