Sunset Riders is a really tough call to be honest.

The SNES version is really more like the arcade but the music is off. It did have all the cool little speech from the villians though.

However, the Genesis version has much better music as I always thought the Genny music sounded more like the arcade. The Genesis version is also about 2x longer than the SNES version as the levels were all much larger, and there were more bosses in the Genesis version.

So my overall decision is that I feel the Genesis port of Sunset Riders is better simply because I always felt I got more of my moneys worth from it.
