[CS] EPFL vs UCSB

[frogstar]

Hi,

I've got offers of admission from EPFL and UCSB Computer Science PhD programs. UCSB offers TA = $16000 for 9 months + tution waiver (inc. non-resident) and health insurance, there is one professor whose research I'm interested in and his former PhD students got decent positions. EPFL offers fellowship of 50000 CHF = $48000, there is no tution cost, EPFL also has one professor whose research I'm interested in. But unlike the professor from UCSB, he doesn't have graduated students because he is an assistant professor (on a tenure track), however he publishes in many good conferences and journals.

I don't know what to choose, any advice? Can you tell what are the prons and cons of each option?

I appreciate your help.
