This mission is rather short and doesn't surpass LotP but it's pretty good and it does one thing which the aforementioned OM did not do: there are people walking the street under the thieves' highway, and that adds a lot to making the city feel more alive despite the player not being allowed to go down there. It doesn't have a big main which is perfectly fine, but there are some unintuitive moments which kind of tainted the experience for me. Still, the mission is well worth checking out; it'll probably take you under an hour to finish and chances are that you'll like this one if you're a fan of traversing the rooftops to break into small buildings.
