I said I'm not sure. Kinda comparing apples to oranges.
"SNES games" is a very broad spectrum of games, hundreds of them, some of which are really high quality games that have stood ~25 years of comparisons. "Indie Games," the ones in the OP, are like... a handful of games over the last few years which are all excellent by today's standards.
I think when people mention SNES or Genesis (or whatever generation they comprise) as like "Greatest generation of games ever," they're not only thinking of Link to the Past, Super Mario World, Super Metroid, Sonic 2, Earthbound, etc., but there's also a tremendous variety of other games that are easy to skip over because there have been sequels or the genre is less common today ... NHL 95, Super Street Fighter 2 Turbo, NBA Jam, Ken Griffey Jr, etc, and hundreds more games that have largely all been forgotten... Games you'd rent for a weekend or buy used from Funcoland that were odd (Cool Spot is a good example, a game that nobody who wasn't alive in the 90s would even really have heard of unless you're really into discovering classic games ... It was a 7-up licensed videogame that was also great). There was a ton of variety from that generation, and while you could probably pick "the best indie games of the last 5 years" and compare them to games from any generation -- especially this SNES/Genesis generation because so many indie games are now sort of throwbacks to concepts introduced then -- it's tough to compare when you broaden it out to the huge variety of games.
I think games like Hollow Knight, Celeste, Guac, and so on, can all stand up against any of the classics from the SNES era... but a lot of these games stand on the shoulders of games from that era. The recent 'MetroidVania' explosion of the last ~5 years (or w/e) would not exist without concepts introduced by original games in the 16-bit or 32-bit era. Like, you could try to pick the best modern indie platformer ... say ... Celeste, or something, and then compare it to the top platform games from the 16-bit era, maybe Super Mario World or Rocket Knight Adventures (or whatever your faves are), and Celeste does things that no game from that era does... Tight platforming, terrific art, great controls (things all those games had), but also a really compelling grown up storyline interspersed into the game (something that almost no platforming game did in the 90s). So, sure, maybe Celeste is better, but it's a hard comparison because Celeste wouldn't be Celeste without those 1990s games setting the template for how to make great platforming games.
One thing that the modern indies have now is that just about every game has a well developed or at least present story. THat's something that most action platformers really didn't have in the 16-bit era. In the 16-bit era, almost every action platformer was "You are a hero who has to save victims from an evil bad guy." Full stop. The storylines were similar to VVVVV or Super Meat Boy, which is to say, they really didn't exist. Your motivation for wanting to be Sonic the Hedgehog was "You are a RADICAL HEDGEHOG who has to defeat an EVIL SCIENTIST and save ANIMAL FRIENDS." Imagine trying to sell a 1990s audience on Celeste, "You are a socially unsure, anxiety-rattled spelunker who has to climb a mountain." But, Celeste has such a terrific, well written story and with Sonic there is no story other than the premise, but it's just something that action platformer games didn't do 25 years ago.
