Knuckles has actual super sonic scaling so yea

I don't know a whole lot about sonic characters but I do know that they all get speedblitzed by DBZ characters. As of my knowledge Sonics fastest form is 9x the speed of light, which is nowhere near anything what the Saiyan's can do. I'll put Frieza saga since I'd reckon that's enough to break through Super Sonic Knuckles goofy durability scaling

emeralds are allowed btw, so if that helps it fan be used

Knuckles was using the master emerald or something like that to knock super sonic out. I forgot the explanation but genuinely believing Knuckles scales to Super Sonic is just.......yeah.

Frontiers kinda establishes Super Knuckles as still being in canon, and even if Super Knuckles is like, a million times weaker than Super Sonic he still sweeps (both draw from the same power source that they are both adept with using so the gap shouldn't be too wide)

Oh, you meant Super Knuckles? Well yeah of course he scales to Super Sonic. I thought you were referring to base Knuckles one shotting Super Sonic, my bad.

I still struggle to understand how people believe Sonic to be some all powerful character. Tbf, it could be due to my unfamiliarity with the series, but Sonic characters (at least in the context of DB) are quite slow. Like, a max speed of 9x the speed of light (for Sonics top speed who I believe is the fastest of the main team) and it doesn't matter how strong your attacks are. They're never gonna land against even Namek SSJ Goku who's countless levels of speed beyond that, let alone any higher transformation/ later version of Goku.

With or without the flames of disaster?

if you think he would, then yes.
