I'll also miss my most favorite quest option that's sadly no longer in the game (since the quest got replaced):
The original quest line for free homes had you hunt down a former tenant to obtain their papers. Said tenant hid in one of the outlaw refuges and demanded a specific task from you (I think you had to get something from somewhere else). At the end of the dialog, you'd have an option like "Okay, I'll do it." However, if you previously completed the Dark Brotherhood quest line (or at least joined them, I don't know), there was an extra option "<Remain silent.>" which would make the guy – a very muscular/bulky man of an Orc! – absolutely freak out, start stuttering, and then immediately handing over the papers, skipping all the busywork.

Being a quest completionist and doing everything in order has unlocked so many little extra lines of dialogue for me. Very happy I stuck with one character through out for all the questing.
There are tons of dialog options in most DLCs (as well as the base game).
For example, if you start in Bleakrock and ask Rana about Argonians while being an Argonian.
Other examples include being a female character while completing the quest surrounding the Mabrigash Ashlanders in Deshaan or asking some Khajiit about Khajiit while being a Khajiit.
One of the quest NPCs in Moonhunter Keep will have a different option after completing the dungeon, if you're a Werewolf, etc.
Also gameplay differences in some instances: I'm pretty sure in the Greymoor prologue you're able to see/skip a few things, if you're a vampire.
Just keep in mind they don't have the same variety everywhere, because I guess it would be simply too costly to do VO recordings for all those lines all over the place.
