since socialism and capitalism is a ideology of the country, it's no single answer that can answer which is better. different people have different point of view, but let me say this as an netral person. all have the pros and the cons, for example in socialism:
There is no market in a socialism economy and therefore, there is no competition. The quantity of products produced and distributed is regulated, including the price that the consumer will pay for the products. While, the capitalism is an economic and political system that is based on the principle of individual rights. It believes that it is inequality that will drive the people to be more innovative and productive.

see the difference?to conclude, i think both is good and always have pros and cons in every sector. but which is the best is depends on the citizen , the way of thinking, and the condition of the country who use that idelogy.
