Tsallis Gaussians can be easily compared with Gaussian and Lorentzian functions, and with pseudo-Voigtian functions too. In fact, for q-parameter equal to 2, the q-Gaussian is the Lorentzian function. In the case of the Kaniadakis Gaussians, the difference with Lorentzian function is appreciable in the farwings, Therefore, being the q-Gaussians the natural generalization of Gaussians and Lorentzians, which are the functions more involved in the Raman spectral analysis, the use of Tsallis Gaussians must be preferred.
