I vote sci-fi: strange alien objects (wild live and items) and alien environments can be used in a fantasy setting too. Like giant mushrooms or other weird plants can fit in the Feywild... And some patrons are otherworldly even some creatures (aboleth, beholder, ...) are alien and can 'customise' their lair.

Thank you for your vote and your totally right there are tons of otherworldly creatures and settings that allow many sci-fi elements to fit right in.
