TIE phantom's useless if you want an ion weapon, no good taking a VT-49 if you want to dodge arcs, Falcon's terrible at blocking.
While you are right about Phatoms and Ions, I think you are missing the mark with those other two. A VY-49 with PTL, Ysane Isard, and Engine Upgrade makes an awesome arc dodger and an ORS is a great blocker.
A PTL VT-49 has a very limited dial, and even if it does boost the boost will only take it so far. That 11 points of upgrades improves its arc dodging ability but it's not exactly playing the Vader or Fel game.
I don't count ORS as a Falcon. It's a YT-1300, certainly, but not a Falcon. TBH it plays like another ship entirely. The lowest pilot skill on the Falcon is 5.
