That depends what you mean by best. The mid to late 80’s were the sketchiest. Worst was indirect - being at the wrong tube stop at the wrong time on drugs not designed for violence after being up for 36hours. Spare you the details.
Plenty of Old Firm games get tasty but it’s saltiness of the working class kind, the sectarianism is pathetic though. Hibs away has traditionally been the “best” for sheer fear and terror. Definitely Hibs, personally, but we all have to grow up. I support Celtic, but follow Forest. Forest‘s Executive lot were such a bunch of muppets, embarrassing.
Not a fan of bullies but the paradox is they litter this specific world. Glorifying it is impossible when you’ve seen wee kids scared and crying caught in the middle of carnage.
