In the context of the Gestalt learning theory (Theory of Insight), how is it fundamentally different from Thorndike's traditional Trial and Error theory, and what is the most prominent feature of its cognitive process?

According to Gestalt psychology, learning is not a mechanical or gradual process, but rather a sudden holistic mental restructuring through insight, in which the organism perceives the various parts of the problem as a single integrated whole rather than viewing them separately. The main proponent of this theory was Wolfgang Köhler.
