I’ll pick the Bowie from Guardians of the Galaxy.
It’s a fast ship that can flown solo, but also comfortably carry six people with their own quarters. It’s fast, can cloak itself and defend itself from anything it can’t outrun or hide from.
I don’t want a big starship that needs a big crew to fly. But, I don’t want a small ship that can’t carry guests.
The Yggdrasill from Hyperion.
The one from The Fountain was kinda similar. It was unique enough to stick with me over the years anyway.
I don’t know if Ringworld really counts as a ship but I loved that too. The Out Of Band 2 from A Fire Upon The Deep seemed like it would be pretty baddass. Or the alien ship from Rendezvous with Rama.
dune’s guild heighliner. there are many depictions of it, but the general idea is awesome (an enormous tube)
The Lynch one is great. The huge baroque hangar doors clearly inspired 40k’s cathedral in space aesthetic
Plus it does that really cool spinny thing and blows away a hundred hostile ships who can’t hit back for some reason.
