They both look very similar and great! But the SNES version has a bit more detail, while the Genesis version has a better aspect ratio and higher resolution, so I would go for the latter.
For me at the time, this game looked and feel in both consoles next to 32 bit 2D graphics. It was even better than some like Iron Man and X0 Manowar for example.
