Dauntless would be my preference in squadrons if 2-3. Itís judt as resilient as the Endeavor but has superior speed- gives you better options on how to deploy those torps.

Endeavor for me doesnít shine unless it is an Ad Mech or Rogue Trader version. AM gets a dorsal lance which makes it a pretty decent gunboat for the price plus you get blessings of the Omnissia. RT variant can get xenotech upgrades and can pay up upgrade the prow to 6+ at the cost of lowering turn speed to 45í which is interesting.

Most importantly is to fly what you think is cool- even the vanilla Endeavor can be good support in a gun line
