Congrats on your acceptances - and on the scholarship $ from UCLA!  A few thoughts:

1) I don't know that I'd use LinkedIn alone as a benchmark - unless you are truly doing a Haas vs. Anderson comparison (and not a Berkeley vs. UCLA comparison) and are certain it's a representative sample, etc.  I'd strongly recommend that you comb the schools individual career reports for the past few years and see what that tells you - especially with respect to jobs at the firms you are targetng. FYI: Data on our school profiles pages suggests that Haas grads make $125K on average right out of b-school, with 37% heading into tech,  For Anderson grads, those figures are $120K and 30%.

2) How certain are you of your ability to live and work in the USA post-MBA?  Do you have a US passport?  If there is a possibility that you will not stay - and will perhaps return to Europe - I recommend that you investigate the strength of each schools' network and reputation in some of the key European markets you might target.

3) As you likely know, Berkeley tends to outrank UCLA in most (if not all) of the major MBA program rankings.  As such, the key thing to contemplate is whether that edge is worth paying the extra $80K...and the answer to that question may depend on your future earning potential; since working at Amazon et al is likely to allow you to pay back loans awfully quick (vs. say taking a job with a non-profit).

4) Attend welcome events for students and make a real attempt to get to know your future classmates and the schools' cultures.  LA and SF are really different cities, and Haas and Anderson offer different campus environments.

Best of luck!
