The difference here is that long haul infrastructure needs a H2 station every 200 maybe 300 kilometers.

For personal vehicles we need orders of magnitude more, because refuelling a H2 vehicle is even slower than liquid fuels.

Its mostly the infrasctructure thats the problem though. Its complex, expensive and overall just less efficient than full EV. Ageing wheels has an entertaining vid of the Toyota Mirai where he discusses the pros and cons of hydrogen. https://www.youtube.com/watch?v=rtZQLUtckS4

Finally, not an either/or perspective.
