There is certainly pros to having cash as pointed out. The appreciation of stock though can be a benefit in that your 200k is still going to be 200k next year,

There is certainly pros to having cash as pointed out. The appreciation of stock though can be a benefit in that your 200k is still going to be 200k next year, while the 200k of RSU could be worth say 300k. So second (and third and forth) year you get 300k a year worth of RSUs, while still 200k worth of cash. So while yes first year of RSUs vs stocks you buy appreciates the same, subsequent years RSUs are worth more (if it keeps going up) because the # of shares granted is locked in. Of course the inverse is also true, if the stock price falls, the # of shares granted is still locked and the value drops.
