If you are dealing with tall, thick grass, brush, and saplings then a bladed trimmer is the better option as they have more cutting power than string. On the other hand, if you are dealing with lighter vegetation, obstacles, and ninety-degree angles then a string trimmer is the better choice as it is safer for cutting around trees and rocks. It’s also important to note that brush cutters require a more powerful motor than string trimmers to operate effectively. Additionally, brush cutters can be slightly cumbersome when using them in large areas.
