Gradient Boosting Regressor builds trees iteratively, where each tree corrects the residual errors of the current ensemble. It typically achieves the best accuracy among regression models in the toolbox.

When to use

Best when accuracy is the priority and training time is acceptable. Does not require feature scaling.
