Finished Orsinium's Main Quest, Looking Forward To Thieves Guild's Main Quest on Xbox One Tomorrow:

After having a lot of fun running and doing stuff in Orsinium I decided to run through the main quest in the Orsinium DLC content pack, and I was rather surprised on the twist in the story line, I will NOT post what the twist is to avoid spoilers, but I will say those who like a good story and want to be surprised should just go for it and do collectibles and side quests later, as long as you're level 40 or higher, any lower and you may have trouble defeating a lot of the enemies. I can't wait to see if Thieves Guild has another plot twist and what it will be, plus I am looking forward to have a Frog/Dragon hybrid pet follow me around.

I enjoyed the Orsinium quest line as well. TG I've found I really, really like the npc characters you get to hang out with.
Make sure you pay attention to the conversations they have in the Den

Overall I liked the Orsinium DLC quite a bit better, but in my opinion the main storyline of the Thieves Guild DLC (and in this I'm including the one-time-only side quests for the various main characters of the DLC, because it feels like they're all relevant to the main storyline) is a little better than the main storyline for Orsinium.

Exactly as was said above. TG's NPCs are really a lot more interesting, Walks-Softly for instance or Silver-Claw and his way of explaining things, lol. But thus far I enjoyed Orsinium's questline somewhat more than TG's and I'm halfway through, so it's just my current opinion.
