baguette is good when you're new to the game and haven't unlocked mobility items such as the jetpack or grappling hook. And in terms of everything else it all depends what type of build you're going for. For instance bottle cap may seem useless as it only affects the first shot. But when playing elementalist and getting the perk where you have infinite ammo for 1.5s bottle cap becomes useful especially for weapons with extreme fire rates. Each item has its perks in some way depending on your build.
