Having been on both sides of this fence, once as a manager, and several times as an employee, I think the idea of "unlimited PTO" is too suspect to smart employees, and the only real viable option as a good (productive) developer is 3-4 weeks vacation, and not complaining about "crunch time". The problems arise when "crunch time" turns into "all the time". It's at that point you've just got to take advantage of this market and make your exit. 2 weeks for the first three years on a job just isn't realistic, when you realize that that extra 10-15K means missing out on things you enjoy or need to take time off for.
