So, what are your top 3 WADs of all time? Mine are as follows:
1) ZDCMP Take #1 - Wonderful huge map that generally takes me an hour to play. Its filled with such diversity in monsters, locales and battles that it never seems to get old for me. Plus it shows a great many cool ZDoom features, which is always a plus!
2) Doom: The Rebirth (by Vader) - A good looking but not particularly high detail megawad with new textures, sprites and a very good classic style of gameplay. One of very few megawads that I've played that I could honestly score above the original Doom in terms of sheer fun. Also cool is the fact that it only needs Doom2.exe to run.
3) Revolution! (by T.V.) - I only played this recently, but the simple fun and highly creative architecture really made my day. I can see why its quite so highly regarded. Although the bug in the first map with the yellow key is a slight pain, that was the only problem I had with it, and again I found it a lot more fun (and replayable) than the original IWADs.
As you can see, I like WADs that I can play for a while but progress through swiftly and hold a lot of variety and a few new things. Much as I enjoy the challenge of mapsets like Alien Vendetta, they aren't the sort of thing I could go back to and play again as the maps are either too long, or there are just too many monsters to make progression swift enough. Fast arcade-y gameplay is what got me into Doom in the first place, and kept me there.
