Which Ships Should a F2P Farm ????

I have GW tokens and some of the new currency to buy blueprints with and I have a bunch of ships that I already have toons for. The question is, which ship(s) is most likely going to help me out the most in these next few weeks. Also I wonder what the Meta for the ships arena will be, any ideas??

Also since farming these blueprints seems to have a bit of RNG involved, I can't reliably farm specific blueprints that I want everyday. Also now that Rex is in the ships shipments (I also saw darth Vader shard btw) would it be better to farm shards for toons or blueprints??
