Their trio of ships is really good but it is literally the ONLY thing they are good for. I prefer double-duty ships that have pilots useful elsewhere.
The old ones would be Phoenix, Biggs, Vader, FOTP, Tie Pilot, Boba, Cassian, KRU, Poe, etc. FOTP and Tie Pilot are a little out of favor but still have spots on teams. You can still take first on an old shard with only those ships.
The shiny new ones would be Ig88, Cad Bane, Bossk. I would farm and gear their pilots and ships first, if starting from scratch. BH have a lot of uses.
Now if the Seperatists get a rework that may change, but you can accidentally get the Geos and their ships to 7* without much effort. Then you can gear them later if there is a rework.
IMHO.
