From my experiences of owning both the warrior and berserker ring, i say, if you only plan on using mainly whip/dscimmy or any other weapon that slashes, use the warrior ring for the slash bonus. If you plan on using other armor like Dh, Veracs, Guthans, ect. get the berserker ring for the str bonus. In my case, I hit roughly the same with my whip with both rings, so clearly, in my case, both rings worked the same with the whip...but thats just me. edit~ to answer your question of which ring is the best, it all depends on the environment^^^
