I don’t have a favorite ship design, they’re all pretty good.
And I don’t particularly have any favorite ships either.
Edit (Gunna expand on this a bit more): I am of the opinion that Spensa shouldn't have a romantic interest and I think that's part of the reason why I like Skyward more. Spensa has a goal I think that should, in a way, be her love interest, and I didn't care about the other characters enough to ship them. Other than Captain Cob, I freaking love him.
I liked Skyward more.
