Pros:
Capable of reaching all 4 basic planets without stops to refuel and without ever taking damage
Doesnt waste cargo space by buffering resources - everything you need is on a beautifull spaghetti
Sushi
Simple design, easy to modify to your liking
Balanced build. 10 furnaces provide 6 a bit more than iron plates per second and its exactly how much iron 2 t2 assemblers making ammo need.
Cons:
Simple design, so a bit ugly
P.S. Blueprint has few uncommon components (solar panels and asteroid collectors), but they are not necessary, common ones will do as well. Specifically solar panels are enough to supply power demand even on Fulgora, so they are kinda wastefull, but i still recommend to at least make 2 front space grabbers uncommon, as they have 2 hands, so they are a lot better. Efficency modules are mandatory tho.
