Dual spec I'd assume STR/DEX. However u should be more specific. Do u mean str equip or dex equip? Also "best" means different things to different ppl. For one person "best" gear on dual spec bear might mean bow with high damage/dps and gear adding damage/crit (ring included); while for others it may mean tanky str gear - sword 'n' shield set with massive armor and dodge. It's all about what do u want to achieve with ur gear and what would be ur task in a party (if u even strive to be useful).
