The VDB layout which makes it possible to render huge sparse-grid volumes makes rendering everyday volumes slower than the dense-grid AUR format.
If you can choose between AUR and VDB, go with AUR when possible. The rendering speed-up with AUR files can go up to 2x depending on the complexity of the setup.
Furthermore, resimulation results when using VDBs as a base usually differ from the results when using AUR filesdue to differences in the default compression methods.
