This site's own "reasonable fit" list names this specific point directly: prefer a simple daily spray over pills or powders.
Worth reading this specifically as addressing delivery-format preference — it does not claim a spray is more effective than a capsule, just that it may suit someone with a stated preference against swallowing pills.
This site separately explains its sublingual delivery choice in more depth — worth reading that fuller explanation alongside this brief fit-list point for the complete picture.
