Comparing this Ambush to its Kitara counterparts Tempus and Forced Connection, I think this one comes out on top. Let's discuss why:

1) Highest base trace strength of the 3 Ambushes PLUS it's in the faction with all the trace-boosting (i.e. NBN: Making News, Primary Transmission Dish, etc.)

2) Does not give the choice to the Runner like Tempus so the corp can choose the most painful card to bounce such as a Dhegdheer hosting a Mopus or a charged-up The Turning Wheel or Net Mercur

3) While 2 tags or a brain damage will hurt, Intake in your scoring server along with NGO Bait can open up a big scoring window for yourself next turn that Tempus and Forced Connection can not

The downsides of NBN's newest Ambush are significant however. It has the potential to do nothing if accessed turn 1 or 2 and it won't set up a win condition on its own like 2 tags can. Its 3 influence is hefty but it shouldn't matter since it'll likely only see play in the new NBN bounce-to-grip archetype that's been fleshed out this cycle. Overall, I'm willing to give it a shot even if its only use will be draining the Runner of 4.
