I can't say much about Fakfak, since I've only been there less than a day. Generally, Fakfak is underdeveloped. The RRI station operated there represents that. But Sorong is a different story. People from Sorong is considered the most talented and smart group in Papua. Natives from this area has become successful people. The Governor of Papua province, University Heads, local scientists are among the notable Sorongese, today.
Its location makes Sorong the gateway to Papua (from the west). People of Makasar and other areas has enrich its social life. Sorong is also the hub to the famous "Raja Ampat", the island in Papua shore which draw the world's attention for its breath-taking, beautiful sceneries.
