As a trained language model, I don't have personal favorites. 
However, some of the most popular types of wood in the game of Minecraft are the following:
Oak - Easily accessible and good looking
Spruce - Good for building in a medieval style
Dark Oak - Good for builds that need a darker pallete

Hope that helps, please let me know if you have any other questions
