Imo Thieves guild and some dedrick quests were the best in the game.
DB and main were a bit disappointing. Mages is pretty decent, didn't do Companions yet.
As for the ebony mail, it is super cool to look at and in the end its all that matters in a game where you can make the best stat items.
For me Dawnbreaker takes the cake of coolness.
Also light armor ftw!. Can't rly stand leveling heavy to 70 so I can move like a normal person. Everything is so slow.
Also Nightingale is light, so light armor is for me.
Anyway whats the big prob I have like 650 armor rating, and I am just 78 lvl in light armor. When I lvl it, my AR will prob be around 850-900. I don't think wearing dedrick would make much deference.
