Both versions of Daimakaimura are full of fugly elements and 8-bit loking graphics. I'd have much prefered a CD port with flat bgs and Forgotten Worlds SCD quality graphics. I think that the SGX version does look better overall, but many things still look better in the MD version. I haven't played through he SGX version many times, but I really prefer the gameplay of the MD version over both the SGX and arcade. The MD version is much closer to being reasonably playable and I can do laps on a Nomad. I like the SGX music best, not only is the soundtrack well suited for PCE, the sound programmer did an amazing job for a pure-PSG soundtrack.
The PCE Strider looks better overall in some of those screen shots where bgs aren't missing, but overall has terrible coloring (yet good detail and tile art), to much formally layered bg art missing and ugly scrolling. I haven't played it in a long time, but Joe mentioned that there is some ridiculous flicker in places, so it sounds like they didn't even try to manage things at all. It really feels like a far from finished port just shipped as-is. I'm not a fan of the game in general, but the gameplay that I don't like didn't seem to far off to me
