SMW, Super Mario Kart and The Legend Of Zelda on the SNES are milestones of the genre, never again has this level of perfection been reached in 2D gaming imho (excluding SMK here).
The Legend of Zelda: A Link to the Past is no. 1 on some all-time best of lists. Maybe its the impression it made on many of us in our youth, but a year ago I played it again, and it was still great. The music, the art style, the controls - its the stuff that nostalgia is made of.
It's not as expansive or elaborate as the snes marios or zeldas, but the gameplay is very polished and deep, and the plot is... well I won't spoil it ;)
Maybe in the arcade, certainly not at home in 1990 and 1991, SMW was one of the best looking games of the time.
Look at the games in 1990:

Some of the best looking games of that year:
SMB3 just came out to the US, SMW was light years beyond it.
Bonk's Adventure was good looking for the time but doesn't hold a candle to SMW.
On the PC we had the original Commander Keen, which while a great PC game of the era, doesn't even begin to approach the quality of SMW.
Secret of Monkey Island was a beautiful game, but it is an adventure game. The screen is mostly static. SMW is far more impressive, being side scrolling and having parallax scrolling of multiple background layers (and occasionally foreground layers as you see in the forest.)
Nothing in 1990 compares to SMW.
If we jump forward to 1992 (by which point SMW is 2 years old):

Then we see Wolf 3D come out for the PC, which was really impressive and of course changed everything. But it wasn't like it made SMW look dated (besides being FPS vs. side scroller, Wolf didn't have very many types of enemies, had static ceiling and floor, etc.)
For side scrollers we have Ecco the Dolphin, which is a cool game but I don't think as visually complex as SMW.
Mega Man 4 looks great but is not doing anything graphically that SMW hasn't already done. It has a different art style that you may personally prefer.
On the Genesis we have Sonic the Hedgehog 2, which looks good but again doesn't have as much going on as SMW.
I'm struggling to find these games that were much better looking. Can you give me some examples?
That said, those kinds of games weren't actually the norm on the Amiga, either - there was far more low-end drek that threw higher fidelity, but artistically underwhelming, graphics on the screen sluggishly and semi-competently(ports from other platforms, licensed tie-ins). Console games did tend to have a higher average level of polish along most axes.
But Shadow of the Beast, while an impressive game for the time and for the Amiga is not on par with SMW technically. You may prefer the art style of Shadow of the Beast, and that's fine, style is subjective. But technically SMW is just doing a lot more. The multi-layer parallax in Shadow of the Beast is only used on the flat levels without any level architecture, Shadow of the Beast has few frames of animation per enemy, and fewer colors per enemy, and fewer colors on screen (128 vs. 256.) I don't have the details of the Shadow of the Beast level engine but it seems like the levels are also made out of much larger blocks than levels in SMW.
Anyway, this conversation is getting boring and like I said I'm really not interested in any kind of "Amiga is the best of all times" shenanigans. I'm not a fanboy of any particular hardware, console, computer or otherwise. Every platform had good games, and things that were good about it and things that were less good about it. This thread was about SMW.
I accept your point about the colour mode, it seems [1] that SMW has more colours on screen as you said.
Regarding the animation frames, I couldn't find info, I'd love to read about it so let me know if you have any good link.
In my parent comment I was thinking more about smaller vs larger sprites (up to 128px in SotB) [1][2], and flat colours vs extensive use of gradients (I don't have hard data on this but it seems pretty evident by just looking at a few screenshots).

(I have spent entirely too much time in the guts of that thing. Send help. And liquor.)
The same is true of Metroid Prime on the gamecube, which looks better than some modern games despite hardware which was underpowered even at the time, due to masterful art direction.
Super Mario did for video games like Star Wars did for sci-fi and special effects.
edit: nm, youtube's list has an electric boogaloo moment. Search within channel finds them just fine.
