San Francisco vs. San Diego: Which is the better getaway?

Reporting from San Diego and San Francisco —  Every year, millions of people find themselves craving a vacation from greater Los Angeles. Many of these people don’t want to cross state lines or climb mountains or contend with deserts, rivers, lakes, waterfalls, redwoods, Gold Country or Mickey Mouse. Which leaves them facing this question: San Francisco or San Diego?

Or, as some people would phrase it: Think or swim?

It is a per-capita fact that one city has more surf shops and the other has more college graduates. But there’s more to this choice than that.

One of these cities gives you reliable sun, a world-class zoo and kid-friendliness, accompanied by the occasional reminder that the 1982 film “Fast Times at Ridgemont High” was based on a true story.

The other city doesn’t seem to care as much about your kids, but it will feed, entertain and edify you with such verve and sophistication that you’ll barely notice the arctic breezes.

One is forever winning popularity contests, but the other is cheaper, has less crime and attracts more than twice as many overnight guests countywide.

One gave us “The Maltese Falcon,” the other gave us Tony Hawk.

One is the cradle of hippiedom; the other is a major Navy port. (See stories online.) One is four times as densely occupied as the other, yet when it comes to hotels, they’re almost dead even -- 226 in one city, 225 in the other.

One city has Balboa Park -- no, check that. Both have Balboa parks. But can you guess which Balboa Park once harbored a nudist colony?

One has the Golden Gate Bridge; one has the Coronado Bridge. One points north to Marin County; one points south to Mexico. One has Market Street -- wait, both have Market streets. San Diego’s is longer, and San Francisco’s is scarier.

One city has a winning football team, and one has the 49ers. Both have losing baseball teams (if you count up the last three seasons), and both teams play in retro-flavored downtown ballparks near water’s edge.

So if you’re a weekend tourist, which is better?

I hereby submit that from dusk to dawn, San Francisco is better. Well, except from November through March, when it can get cold enough to frost your Irish coffee.

I further submit that from dawn to dusk, San Diego is better. Especially if you get outdoors a lot or you’re a kid.

Oh, but San Francisco will be better July 22 to 25, when 126,000 Comic-Con people will clog downtown San Diego. And San Diego will be better Sept 19 to 23, when 45,000 people gather at San Francisco’s convention center for the annual Oracle OpenWorld information technology conference.

To arrive at this richly nuanced answer, I made fresh visits to each city and weighed the data with absolute objectivity and seriousness, except for the parts that I goofed around with, which follow. Your results may vary.

Getting there

San Diego: To reach downtown S.D. from downtown Los Angeles, you’ll probably drive. It’s about 120 miles south, two hours on a great freeway day, four hours on a rotten one. Expect a round-trip gas bill of $36 if you get 20 miles per gallon and pay $3 a gallon. If you take Amtrak, it’s a little less than three hours and $29 per adult each way.

San Francisco: From downtown L.A., drive north about 380 miles (round-trip gas bill: $114), six hours at best. Or you could fly, probably paying $100 to $200 for an LAX-SFO round trip. Amtrak? Too slow and complicated.

Getting around

S.D.: Sprawl with a pretty face. The San Diego Trolley takes you from downtown to Mission Valley or the border, but to reach the beach, you’ll probably be driving. Taxi licenses? 1,222.

S.F.: Cable cars, BART, the Muni system and 1,432 licensed taxis working an entire city that’s about 7 miles by 7 miles, give or take.

Eating

S.D.: Despite the great fish tacos, S.D. is rarely counted among the planet’s best cities for eating. For 2010, the Forbes Travel Guide (which recently swallowed Mobil’s influential restaurant-ranking operation) deemed 58 S.D. restaurants worthy of ranking. One got four stars, and one got five -- Addison, at the Grand del Mar hotel.

S.F.: Is always popping up on somebody’s list of world’s best restaurant cities. For 2010, the Forbes people deemed 125 S.F. restaurants worth ranking. Nine got four stars, and one received five: the Dining Room at the Ritz-Carlton.

The city as a muse

S.D.: Inspired Max Miller (who wrote the gritty 1932 novella “I Cover the Waterfront”) and must have somehow influenced Dr. Seuss (Theodor Geisel), who lived here about 40 years. Tom Waits (“San Diego Serenade”), Frank Zappa and Blink-182 played in their first bands here, and Jewel and the Stone Temple Pilots got big breaks. At the movies, it was either the set or inspiration for “Top Gun,” “Traffic,” “Anchorman: The Legend of Ron Burgundy” and “Fast Times.” On television, “Simon & Simon.”

S.F.: Inspired Dashiell Hammett’s detective novels (including “The Maltese Falcon”), Douglass Cross (who wrote the lyrics to “I Left My Heart . . . “), and many classic-rock performers, including the Grateful Dead, Jefferson Airplane, Janis Joplin and Santana. At the movies, it was the set for “Dirty Harry,” “Bullitt” and “Milk.” On television, “The Streets of San Francisco” lingers in memory.

The college crowd

S.D.: The U.S. Census said that, in 2008, 40.7% of residents 25 or older had bachelor’s degrees. San Diego State counts about 27,500 undergrads; UC San Diego counts about 22,500 and University of San Diego (a private Catholic university) counts about 5,100.

S.F.: The U.S. Census reported that, in 2008, 50.3% of residents 25 or older had bachelor’s degrees. San Francisco State reports about 24,000 undergrads, UC San Francisco reports none (its more than 4,000 students are all grad students in medical subjects) and University of San Francisco (a private Catholic university) counts about 5,500.

The international crowd

S.D.: 25.5% foreign-born, by count of U.S. Census, 2008.

S.F.: 35.6% foreign-born, by count of U.S. Census, 2008.

The LGB crowd

S.F.: It’s not just the Castro. That 2006 UCLA study estimated that gays, lesbians and bisexuals amounted to 15.4% of the city’s population.

What travelers say
