Each option is great, so it depends on what factors you prioritize. I vote Pitt b/c its cons are less significant than UCLA's. Pitt has the lower COL, less traffic & better public transit, & you seem to like the city better than LA (in general). Support is essential, so being closer to family & feeling more supported by the school seem huge. It doesn't snow in Pitt as much as one might think. Research is great at both schools; not that it means much but Pitt is slightly higher ranked in NIH funding.
