If they'd used a decent pallete, the ACD version would look strikingly similar to the arcade, probably about as good as the Forgotten Worlds port.
I'll have to totally disagree with you on this one. I've always thought FW(Lost Worlds) was a very decent port with great use of the palette. I played PCE-AC Strider on the TV (two different ones) with the real hardware and it appears to be worst than the emu shots. What brings PCE-AC Strider down is the accumulative problems and in comparison to its release date. It's not GA, but its close.. too close (relatively speaking).
I also think that FW is amazing. What I meant was, Strider has lots of detail, but with different colors than the arcade. If you gave it the right colors, the
still graphics would look very similar to the arcade. Just look at the arcade and ACD screenshots above, pretty much the only difference is the pallete.
As for Strider on TV, as I said earlier, it loses more than most games through composite, but it does look like it does through emulation when using S-Video.
Although it's probably scrolling at 60 fps, Strider ACD doesn't have perfectly smoothe scrolling. The pacing is off and it gives it a jerky look, similar to GA(from my memory), but not as bad. Again, fixing this one problem would make a big difference, but the other problems would still drag it down.
I think its very far from close to GA. Strider actually uses the arcade graphics and keeps everything reasonable proportionate and full screen.
Golden Axe is severely letterboxed, is completely redrawn in a bad way(unlike the early Capcom Genesis ports) with small sprites and jerky scrolling(from what I remember). Plus the sfx in GA are are fewer and not as good.
Here's a video clip of the first Stage of Strider ACD-
