It is ok-ish, but not great. I think at this point it may actually be worse than LA's, which has improved its system considerably in the past 20 years. Among various complaints: SF Muni is rarely on time and very slow, especially if you need to go east/west. The two main crosstown routes, the N-Judah streetcar and 38-Geary bus, travel just slightly faster than a brisk walk, and are badly overcrowded. The connections to even nearby areas outside of SF proper are fairly spotty also; BART and Caltrain (and to a lesser extent, ACE and Amtrak) combine to make something halfway between a subway and a commuter-rail network, but not one sufficient for ~8 million people. A lack of integrated tickets between all the systems is an annoyance. On the Valley side of things, the lack of success of the Santa Clara VTA Light Rail hampers overall ability for people to commute to/from SF and the Valley without cars—the VTA built 42 miles of track but much of it on a very odd choice of alignment that makes it not useful to that many people.
