Data on hydrogen filled dirigibles is hard to come by, but I think modern commercial airliners crash less often than them.

Certainly, the 1930s ones do not look good. The first Graf Zeppelin made 590 flights before being scrapped, the second 30, and Hindenburg crashed on its 63th flight. That’s a crash in less than 1000 flights.

For comparison, https://en.wikipedia.org/wiki/Boeing_747 says “The 747SR had an economic design life objective of 52,000 flights during 20 years of operation, compared to 24,600 flights in 20 years for the standard 747.”, so I assume Boeing thinks there’s a good chance those airplanes will live that long.
