I will post mine in two catergories. My Favorite Bad tie in: My Favorite good tie in: (I have Topaz AI upscaler for videos at home, it has been really tempting to up this to 4K)
I think the ice cream one is by far the best one, it's not even a competition. I also really like this one where a kid falls and starts seeing Team Sonic in their Sonic Heroes' models, and Sonic basically tells him "Here, eat some unhealthy stuff, you're in serious need of it!"
There are so many McDonald's ones that make me laugh from throughout their history of partnering with Sonic. By the way nice PFP I love RWBY and Penny is one of my 4 favorite characters others being Neo, Roman and Blake
this one ad for sonic yogurt i find this one to be unusually ahead of its time, like a OOPArt. it came out way before there were proper sonic cartoons, and it has a high amount of polish that wouldn't really be seen again for a couple of years
For me, it's the Sonic 3 McDonalds promo so far. The commercials were cool, so were the toys. Even the sweepstakes thing.
This one's funny because you can obviously tell the writers never played the game. Level 10 is Wing Fortress, unless you really stretch it and consider Wing Fortress and Sky Chase one zone.
food. This has always been my favorite, I love the absolute absurdity of everything. I use the "food." phrase a lot in my day to day life. Check out that Mushroom Hill footage with the Chemical Plant music!
