Doing many repetitions with light weights will elicit a different physiological adaptation than doing few repetitions with heavy weights. In particular, your body will become better at lifting light weights for many reps, but you won't get necessarily stronger. If your goal is to get stronger, you want to train by lifting increasingly heavier weights (progressive overload). Any other training strategy, is less efficient, for the purpose of getting stronger, or simply ineffective.
And what I'm saying is that you can achieve progressive overload with harder variations and more time under tension. There's plenty of ways to keep you in the strength rep range using kettlebells and/or calisthenics.
For pure strength and size nothing beats barbells, I already said that, but unless that's your only goal, kettlebells can be an alternative.
