Where do you place your hands most often? STI or Ergo makes sense if you ride with your hands atop the brake hoods, but barcons are great if you ride either on the drops or on the hoods. Barcons are also more repairable, durable, and reliable than STI, and they are wonderful on those "God help me!" multicog downshifts.
