I'll be surprised if anyone is able to provide an authoritative answer
here. There are a number of factors that contribute to how PHP performs
in a given environment. You may just have to benchmark it.

That said, I suspect that using PHP to gzip the stylesheets will yield a
faster page-load time than not compressing them at all, given the
file-sizes you describe.

Please do share the results if you elect to perform benchmarking. I'm
curious :).
