Iit is difficult to make it to Division III (at least in the US). Therefore, I think you should utilize every effort to remain in the aforementioned division. Upon relegation, you may find yourself in a relatively tough D.IV division. As such, you may remain in this D.IV division for multiple seasons (or longer). Bottom line: fight like hell to remain in D.III because you may wind up stuck in D.IV hell for an relatively lengthy period of time.
