It's likely the second or third most profitable route, which is probably why Amtrak upgraded it to "higher-speed" rail (reaching 110 mph) over the past few years. But delays are still frequent and the trains are aging, so a further update would be welcome.

I'd put the Pacific Sunliner from San Luis Obispo to San Diego up there.
