Ships to keep for casual play as a board game

As an x wing player I collected a load of ships when I heard armada was being discontinued. I ended up getting them all, with some multiples of the smaller ones. However, I’ve yet to play it due to the tastes of my different gaming groups, and even x wing hasn’t been out, so I’m going to downscale to pay off some wh40k incurred debts. However I would be keen to keep the core set and a couple of fun or thematic ships to play more as a board game that is fun to play once in a while. Does anyone have any suggestions what ships I should keep? Ideally lower value ships, or ones with fun mechanics. Thanks
