Why I Still Use RSS
Having only the content I want to see only be shown when I want to see it with the freedom to jump between readers as I please, all with no ads? For me, no other service comes close to the flexibility, robustness, and overall ease-of-use that RSS offers.
I would say "feeds" instead of "RSS" as they come in different flavors (RSS, Atom, JSON feed, etc.), but the use case is the same.
