Omega DLC was pretty mediocre, typifying much of what's wrong with ME3. Basically just go from point A to B, shoot at Cerberus goons, and pick one of two dialog choices now and then. The "hub" was pretty much not a hub at all, basically two rooms with some folks standing around chatting idly. Side quests were pretty much "press the A button when you see a terminal along the way."
The new character was cool, but they didn't do much with her before tossing her to the side. The new enemies were interesting but anticlimactic, as was the entire mission itself. Most of the new weapons were already available in other forms elsewhere.
The only really worthwhile aspects for me were seeing the beautifully rendered Omega skyline, which brought back pleasant memories of ME2 and the last area from ME1 (climbing up the council chamber exterior), and the fact that there was SOME character development with Aria that was dialog dependent. Based on your dialog choices, her personality changes and you get (slightly) different outcomes. That would have been par for the course in the first two games, but here it feels like a major treat in a game that was so largely devoid of actual role playing.
The fact that this cost $15 is kinda pathetic TBH, but I enjoyed it regardless. Still pales in comparison to what the franchise used to be.
