RSUs are worth more due to tax implications?

I'd rather have a dollar now versus the equivalence of a dollar in a stock which is unavailable for up to 4 years...

Even if your companies stock is out performing the market, I'd rather have a dollar now to buy company stock and keep my mobility.

Employees need to be careful to diversify their portfolio. A dollar today can be put in any type of investment, whereas RSUs can lead to folks having too much of their egg nest in one basket.
