Net Weigher or Gross Weigher Which is Better?

Hello all, I’m in need of information regarding the difference between a Net Weigher and a Gross Weigher in terms of packaging. I hope you all can offer your advice as to which is better in terms of accuracy and efficiency. The Net Weigher weighs the product before it is filled. This is quite accurate and faster in terms of packaging. However, in a Gross Weigher, the product is weighed together with its container. This is ideal for simple operations. These two types of Weighers are commonly used in various industries such as agriculture, food processing, and chemicals. Which Weigher do you think is better: the Net Weigher or the Gross Weigher?
