We present a critical comparison between conventional Mössbauer spectroscopy on the one hand and energy and time resolved nuclear resonant scattering on the other hand. The three Mössbauer techniques are evaluated by the characterization of the complex magnetic structure of an Fe3Al alloy. It is shown how the different scattering processes and detection schemes, which are involved in the respective configurations, determine the specific strengths of the three techniques and how they are optimally suited for the characterization of materials of varying complexity and reduced sizes.
