hstore querying is quite slow (and GIN indexes on hstores are pretty massive). I'd always go jsonb over hstores these days, but jsonb has the same indexing problem. JSON has a well-optimized/spec compliant serializer/deserializer in every language you can imagine as a baseline, whereas hstore does not.
