For me it really depends whether I'm playing her as Ten Thunders or Outcasts, as you end up with very different crews and playstyles.
For Ten Thunders, I normally bring her out when I want a highly mobile master who can deal damage. I find Misdirection is a must, especially when Frame for Murder is in the pool, but upgrades can tool her to different styles. I guess the main decision comes down to what I need to achieve. If a high kill-count is required (Dig Their Graves, Quick Murder, Eliminate the Leadership, Collect the Bounty) I find she often edges out the competition. Frame for Murder tends to nudge me more toward Shenlong so I can try and kill with conditions instead, and scheme marker shenanigans might push me more toward Lynch.
That said, I don't play all TT masters, so take my words with a pinch of salt
