Why use pstree over ps for visualizing process trees?

I'm exploring various command-line tools for monitoring processes in Unix-like systems and am trying to understand the unique advantages of using pstree compared to the ps command. The ps command offers options including --forest and -H that can also visualize process trees and highlight specific processes.

Could someone explain the specific benefits of pstree and are there scenarios where pstree is definitively superior to ps? I'm particularly interested in cases where highlighting processes and compressing process tree branches are critical for day-to-day operations.
