Silicone squeeze bottles vs. rigid plastic bottles, which is better?

Silicone is easier to squeeze, gets the last drop out, and tends to seal better under pressure, but r/onebag posters note it can absorb scents and leach over long-term storage. Rigid PET or HDPE bottles (like the Cosywell flip-cap style) are easier to clean, better for long-term loadouts, and preferred for thin liquids that gush out of soft silicone.
