There are too many things to list, but
other than a few reasonable people, those who didn't just say that "everything other than SNES sux -end of discussion" and literally exited the discussion, the rest have such misguided understandings of hardware and how games work that incorrect arguments are replied to with equally incorrect ones and it just snowballs.
I'm pretty sure someone said that it's only fair to compare Mode 7 effects to effects on Mega Drive only in cases where the SNES looks better.
In general, the die hard SNES fans seem to think that the SNES is capable of
any kind of scaling and rotation (
Galaxy Force 2 was used an example of what only the SNES could do).
Guyome seems to think that ram = power and that it was the power to render larger sprites and such, not simply additional frames of animation that select Saturn games required a ram cart for.
I like how shubibiman called Guyome on the classic "transparencies only count when they're rendered by hardware" aka "I only count the stuff that makes my favorite console/game/etc look best".
Under 'Genesis pros', it looks like Joel ARRAULT basically said: "It has the arcade feel". Just awesome.
He also literally called Guyome on the above mentioned cliche: "In fact the thing with you is that you speak only what suits you at a time "t", possibly obscuring everything else."
Someone should mention that the SuperGrafx Axelay demo includes several additional PCE roms that do the same effect. That Axelay demo could be reproduced identical on PC Engine with the criss-crossed bars merged onto the other layer or possibly appearing to be double layered using animated tiles.
I think that the fact that the topic was "THE SNES game impossible to reproduce on Megadrive" and not "SNES & MD games impossible to reproduce on the other" sums up the intended bias.
