EECS is first-class citizen at UCB.

Penn CS is 2nd class citizen at Penn  (Wharton is first-class)

Job prospect: EECS wins over Penn CS (for tech jobs).  Hands down.

Cost: huge difference. Save the $150k for something else.  May even use as seed fund for a startup?

Location: UCB is so much better than Penn (for tech jobs)

Rep:  Berkeley (undergraduate) is pretty much at mid-ivy level.  For graduate school, UCB has better rep than Penn.
