In the context of clean polygonal modeling, maintaining a low polygon count is essential for optimizing performance, particularly in real-time applications such as video games. A lower polygon count reduces the computational load, which can lead to smoother frame rates and quicker rendering times without significantly compromising visual quality.

Using consistent polygon size ensures that the model has a uniform appearance and makes shading and texturing more predictable. This approach aids in achieving a cleaner, more professional look since variations in polygon size can lead to artifacts and uneven surface details.

Avoiding unnecessary vertices helps in reducing the complexity of models, making them easier to work with while also enhancing performance. Eliminating excessive geometry that does not contribute to the form or function of the object is key for efficient modeling practices.

On the other hand, keeping the polygon count high does not align with these principles, as a high polygon count can hinder performance, complicate the modeling process, and lead to inefficient resource usage. Therefore, it is considered a guideline that should be avoided when striving for clean polygonal modeling.
