Verilog gives you enough rope. Once the design gets past toy size, you spend time chasing sim vs synthesis mismatches because the language leaves ordering loose in places where humans read intent into source order.

VHDL's delta cycles are weird, and there's edge cases there too, but the extra ceremony works more like a childproof cap than a crown jewel.

Do you consider 800+mm2 slabs of 3nm of silicon still toy size? Because there's a very high chance that those were written in Verilog, and I've never had to chase sim vs synthesis mismatches.

Yes. If you don't know what you're doing and don't follow the industry standard practises.

That does sound like my experience…
