Rule of thumb: when do you pick XGBoost vs LightGBM vs CatBoost?

Answer

  • Roughly: LightGBM is fastest and often top on large, mostly numeric datasets with many features; leaf-wise growth needs careful maxdepth  /  numleaves\operatorname{max}_{\mathrm{depth}}\; / \;\mathrm{num}_{\mathrm{leaves}} control to avoid overfitting.
  • CatBoost is the safest default when you have many high-cardinality categoricals or you want strong out-of-the-box performance with less tuning.
  • XGBoost is a great generalist — the most feature-complete API, best community support, and slightly slower than LightGBM but often a hair more accurate.
  • In competitions, all three are stacked.
Check yourself — multiple choice
  • They are all mathematically identical
  • LightGBM = fastest large numeric; CatBoost = high-cardinality categoricals and low tuning; XGBoost = generalist
  • Only XGBoost handles categoricals
  • CatBoost is only for tabular vision data

Speed vs categoricals vs generalist — pick per dataset shape (and stack them in comps).
