First Premium Coal ship

Hello, looking for some feedback on a ship to be my first coal purchase. Looking at a premium to farm credits with and I am playing on PC, with currently tech tree unlock being: Montana, Baltimore, Mahan, Kagero (only missing credits to unlock T9), and an assortment of random ships from events or dockyards, none higher than t8, and a few other lines up till maybe t5. Current premiums I own...Sharn, Gambia, Yahagi, Kalmar,
I play mostly randoms, just started ranked, and occasionally do ops, but much less up to this point.
As you might expect since I'm looking to buy my first coal, still pretty new, maybe 5 months in, so not looking for anything to high skill cap or technical.
Thanks!
