This one is too case by case subjective to me. In general, I like the NES sound font more than the Genesis, but the SNES comes out on top, yet there is no way on Earth you'd hear something like Shinobi 3 or Thunder Force IV on the SNES. The Genesis to me has the most distinguished and nostalgic sound to it, it can really take me back even when I'm rocking out to some game music of a game I didn't play growing up... that thick chunky chip sound is just too good. But I think the Genesis can have some nasty stuff too, like Carnival Night from Sonic 3... literally makes me nauseous almost or induces a headache. I never really have extreme dislikes for bad/average songs on the NES or SNES though.
Now that I'm listening to a lot of VGM podcasts and discovering even more, I am finding that I really, really enjoy some good Sega Master System and Game Gear tunes as well, and it's almost all purely new material to me since I didn't grow up with either of those. These chips have a very smooth sound to them, ethereal and atmospheric, and as VGM Jukebox loves to joke the SMS kind of has this melancholic sadness to a lot of games. Really cool stuff.
- you can't get that smooth on the NES
Big fan of the GameBoy music too when done well, it's amazing.
Funny enough, I pretty much hate the GameBoy Advance sound font. I really can't speak highly of anything from it other than those Castlevania's having amazing music, as always. And the GBA version of FFV is my favorite localized version of FFV, I do like how some of the upbeat or battle/intense tracks have a heavier sound and bass to it, but yeah. In general, not a fan of the GBA sound at all.
Also don't care to say much about the N64 in retrospect here. I love how weird, minimalist, and dark the Zelda games sound, so those are home runs. And Rare knocked it out of the damn park with Goldeneye, but more importantly Perfect Dark which is probably my favorite N64 OST in general. But beyond that and like F-Zero X or something, I don't know. It doesn't really have much character and a lot of the music just blends in. And it's not like by this time I needed CD quality, in fact I was a hardcore Nintendo kid and didn't touch the PSX until later so I had no comparison, but even back then...
I wasn't having Super Turrican like freakout moments to music while playing anything on the N64 as a kid. It's too muffled, muddy, and not melodic.
Speaking of Turrican... I haven't even touched much Amiga stuff, but its sound is GODLY. Thank you Chris Huelsbeck. And if there's one guy that probably could have challenged the Technosoft Genesis sound with the SNES, it's Huelsbeck.
The PCE feels like a console gold mine just sitting there waiting for me. A strange era between the 16/32bit times... I'm sure there's probably plenty I'd love on it, game wise and musically.
I have a huge fondness for 90's CD music as well and actually would argue that it's very distinguishable. The lower quality recordings and heavier use on samples and synths makes it magical to me and along with chiptunes, feels like a lost art with games nowadays being able to use full on orchestras or whatever. So I think the Sega CD, PCE CD (Rondo of Blood is one I've played), PSX, Saturn, and 90's PC games in general, etc are actually very distinguishable and charming to me. For even some mainstream comparisons just go listen to Starcraft again, you never hear anything that sounds quite like it today.
Anyways, there's no way I can give a final answer on one, it would be an extreme death match between the
NES and
SNES for me.
