Lanczos interpolation seems to beat a gauss filter for me. It has some overshooting/ringing effects of course, but the improved sharpness is a great tradeoff compared to the blurriness of gauss filtering. Of course, gauss filtering might still play a residual role in analog systems, such as the one that physically displays stuff via a CRT screen.
