The problem I have with Jemison right now is that it takes a TON of work getting to 7 points, while leveraging its ability. Every score is typically one step forward, two steps back. You can play a typical game, have scored 5 agendas and still be at 4 Agenda Points or so. That's nuts. People making the claim that using the ability reduces the agenda density for the Runner, should also consider the flipside. I.e. every agenda the Runner steals is one less instance that you can use your ID.
Also, the big overarching problem remains the Weyland cardpool in general, and its incompetent ICE in specific. You obviously want Hostile Takeovers to get things rolling, but every Bad Pub you accrue while scoring makes you so so vulnerable to the Runner's gameplan, whether it's Medium, Indexing + Mad Dash or just plain remote locking.
Oberth is the star of the pack, regarding Weyland cards. But again, how are you protecting it, so it can last for more than a turn and actually have an impact?
