I tend not to use legendaries in-game anymore. It just feels weird battling random trainers with them.
There are exceptions if I happen to really like that legendary, like Rayquaza or Deoxys. --- "Combine Cloak and Dagger with Boots of Swiftness so CC doesn't stop you from moving faster toward defeat." - Frost_shock_FTW
Depends on the Starter and Legendary. For example, if I played Diamond, I'd value my Infernape over my Dialga. But on White 2, Swords of Justice > Samurott. --- I'm not easily impressed; I'm usually oblivious to whatever's in front of me. Pokemon White 2 FC: 4342-3001-3593.
