My wife doesn't use a scale, and she is a much better cook than I am. Her recipes are more inconsistent because she often doesn't measure at all and doesn't always use the same ingredients. But they are always good. The joke around our table is that she only makes a recipe once because no two are the same. But, my wife doesn't make bread and struggles with pie dough.

I tend to use a scale, but that is because I worked as a donut cook for a while and we weighed everything. My bread and pasta turn out the same every time.
But I tend to be a bit more obsessive about doing things 'right'. I've found that as I cook more, I have started to measure less often. For example, recipes never call for the correct amount of cinnamon or vanilla, in my opinion. They just give suggestions.

So … pick something that works for you. I would suggest that those learning to cook use a scale until they can just tell when it's right.
