Strong decays of $X\left( 3915\right) $ are analyzed from two quark model descriptions of $X\left( 3915\right) $, a conventional one in terms of the Cornell potential and an unconventional one from a Generalized Screened potential. We conclude that the experimental suppression of the OZI allowed decay $X\left( 3915\right) \rightarrow D\overline{ D}$ might be explained in both cases as due to the momentum dependence of the decay amplitude. However, the experimental significance of the OZI forbidden decay $X\left( 3915\right) \rightarrow\omega J/\psi$ could favor an unconventional description.
