I've had success with both of the following in playtesting. My meta is largely "homebrew" lists with only a handful of truly competitive lists. Worst case scenario I will face one opponent flying TLT spam, one flying Palp/Vader/Soontir, one flying Bug Zappers, and/or one flying a TIE swarm. The rest of the players in my meta tend to take too few ships with too many upgrades, or else focus on cute synergies rather than true robustness in a competitive sense. I've had good success with BBBBZ in 100pt matches because most of my opponents just aren't prepared to face the onslaught of red dice and lots of hitpoints, and there's exactly one player that has the skills to consistently outmaneuver me with aces. Based on that experience...

It sounds like you have a good handle on your meta. If it is as you say, then either list will be effective. If the 'worst' opposition you expect to face is palp shuttle+vader+Fel, then either list can beat that matchup (although if its 120 pts, its gotta be something more than that, unless a whole lot of extra points sunk into those 3 ships...)

Anyway, I think it depends on what do you fear the most? If its the Vader/Fel + palpmobile, perhaps changing the 3 shuttles into a gunner+vader Decimator would give you a huge edge. Dash +3 T70's has potential against that same matchup if you are good at blocking though. If TLT is your worst fear, then Your 3 shuttles + Soontir will be good. If its swarms, then Dash + 3 T70s should have little trouble...

Fel with PTL SD AT and title.

Have not yet lost with the following list, but again I think that has a lot to do with sub-optimal lists flown against me.
