If you receive $100k worth of stock, you receive $100k worth of stock. If you receive X amount of stock that vests in 1 year, and at that time point it happens to be worth $150k, then you didn't receive $100k worth of stock, you received $150k worth of stock. The question wasn't about comparing $150k worth of stock to $100k cash, the question was about comparing $100k worth of stock to $100k cash.
