For me skipping 1_2 hour of printing time is a win, and saving a bit of pla is not too bad either. Also, a print complely covered in supports could be quite a pain to clean.
Superglue+bakinsoda to close gaps and streight small parts (as the tentacles) > A light sanding > Car primer and wet sanding (standard first then 1200p) > repeat until it looks good enough 👌💫
