The Krenim Imperium Warship is a DPS beast and has a versatile Bridge Officer and console layout. Very fun to fly. The Timeline Analysis console provides a great alternative to Sensor Scan in pvp for Tacs and Engineers.
The Zahl Heavy Cruiser is also a very capable ship. The boff seating and console layout allows for tank builds without losing a tactical edge. The Super-Charged Temporal Shielding console further adds to the tankiness of the ship.

But honestly I think the Year of Hell Lock Box really shines with the Nihydron destroyer. When upgraded to T5-U, the Nihydron ship gets a 5th tac console and the Destroyer package of Mastery leveling. Along with great maneuverability, this destroyer is quite capable. Add in the fact that the Nihydron ship can use both of the aforementioned Coalition ship consoles and you have quite a good ship for a consolation prize. I highly recommend anyone who flies tac ships to get one of these bad boys and upgrade it.
And here I am analyzing the timeline.
