If you are building an engine today (~2023), Professionals are not building Hydraulic FLat Tappet camshaft engines? Don't try?

I only use hydraulic lifter when the end user isnt capable of lashing valves CORRECTLY.

Sadly, too many guys aren’t capable of that. So they get junky assed, leaky, squishy lifters and they can live with the noise they make when the lobes get even the slightest bit agressive.

Other than that, there is no reason to run hydraulic lifters. I say they suck. And I’m not wrong.

If you're building a modified engine your right, if not you are wrong. imo
I've used Rhoads lifters on a few builds and they worked out good.
I actually like the sound of them over a solid.
Otherwise for a stock or slightly warmed over build, a good hydraulic fits the bill. imo
