What are some good horde mode wads? I've tried Zandronum's basic Invasion and Shotgun Frenzy so far, and they felt like they exist on a spectrum of too little or too much going on, and whether they deviate a bit too much from the Doom feel. Reelism 2 is great, but GZDoom is a drag for online play and so far the mod doesn't properly work with co-op anyways. I've got Hordamex and Stronghold: OEC to try soon, but Odamex is kinda eh even though it works, and Stronghold sounds like it's actually way more than just wave defense.
