Ok so I'm gonna try to do this. I've been listening to nin since broken came out and first saw them in 94.

1. Broken/Fixed
2. TDS
3. Still
4. The Fragile
5. PHM
6. Year Zero
7. Trilogy
8. The Slip
9. Ah-Witha Teeth- Uh
10. Hesitation Marks
11. Ghosts

I HIGHLY doubt anything will top broken and fixed for me. I've loved every era of NIN but my favorite was pre internet, when we didn't know much about the man (I misread his name as Renzor at first) and the music and aesthetic had a "goddamn this is horrifying but I can't look away" quality.
