Hard to say, really. The Genesis port tries hard to imitate the arcade version in terms of both graphics and level design but since it's missing two of the characters, it's a really hard sell. The PCE version does not try to imitate the arcade version, the graphics are a bit different and the level designs have quite a bit of variation from the arcade version, all four characters made it in. It's a matter of taste, really...my first experience with Cadash was the TG16 port, and after playing that so much, the arcade version just felt weak, since there was so much added to the PCE version to make it more enjoyable.
