Good WADs to adapt to newschool gameplay?

I've been slowly adapting to the rougher-and-tougher gameplay of more modern wads slowly, but am just curious on some good WADs to help me get better at it. But yeah, I get it, practice makes perfect. Just wondering so I can discover some potentially great wads and get better at one of my favorite games (and pasttimes).

Brutal Doom/Project Brutality (I'm serious)

They will help you get rougher and tougher for modern WADs.

I've always thought Vanguard has a good difficulty curve that does this pretty well.

I've heard good things about that WAD, I'll check it out.

And Ancient Aliens, if we're talking about megawads.

While you're at it, try some BTSX, or even Bloodstain.

Just beat Hell Revealed 1 and 2 like I did and you'll never raise an eyebrow at another Cyberdemon again.
