What is the best meshing tool?

I am currently doing wolf dynamics introductory course to openfoam and I just finished the module about meshing. In that module, the viewer is introduced to the ability of converting a mesh generated by a third party to openfoam format and I am curious if there is a particular meshing tool that generates the best mesh that you can get in cfd or is the idea of "the best meshing tool" subjective to the geometry and physical phenomena the modeller/engineer is working with?
