I've never used anything from Crower before.

I do use the HLJ lifters on the hydraulic flat tappet stuff when I can find them but I honestly don't do a lot of flat tappet cams. I mainly stick to rollers and even then I'm picky about the rollers I use.

My flat tappet cam stuff has stuck with Comp primarily, and some Crane back before they shut down so that's been a long while. I've never had an issue with them.

Probably the oldest setup that still works fine is the Nomad that has a very old solid flat tappet grind in it and I'm trying to remember if it's a Clay Smith or Isky. That's been together since 1972-ish lol.
