was wanting to ask- thoughts on the Trafalgar as compared to the Atlas?

Both good, bad, and neutral. one of my engineering captains is running an atlas as his main-

a combo of aggro drawing/tanking, and repairs/support, with a bit of damage/debuffing on the side (pulsed phaser arrays-phaser transfer ftw).

id been hoping for something like the Trafalgar for a VERY long time,

but ive heard its quite different from the Atlas- no hanger, amoung other things?
