The man is hands down the best character in Skyrim.
"They are in awe of me over there."
Also, while it's great to hear the old Morrowind music again, I have to say, some of the new songs that came with Dragonborn are among my all-time TES favorites. The one with the muted french horn solo.... great.
Not sure how either Farkas or Lydia could even come close to surpassing Neloth. Neither have any personality. Lydia in particular is just a drone-slave.
Neloth on the other hand though, what a guy. "Yes, yes. You're Dragonborn. We're all very impressed." is my favourite line of his I think.
