If you want strength, use barbells.
If you want endurance, go for a run or push a prowler.
If you want mobility, do yoga.
If you want an okay but not great amount of each of these things, use kettlebells.
I do find them a useful teaching tool for certain movements, for example the goblet squat often looks better once you put a weight in someone's hand, and if someone's got a good swing they'll figure out the barbell clean or snatch a lot more quickly. But they're far from essential.
