The automotive Slime is better at punctures than the bicycle Slime-if that is your question. The automotive Slime is designed with larger pieces of solid for blocking bigger holes.
But I think you were looking at comparing the automotive Slime to the tubeless bike compounds- that white colored stuff used at sealing the tire to the rim- and I don’t a strong opinion since I don’t run tubeless bike tires.
My guess is Slime is poorer for sealing tires to the rim since it has propylene glycol and solid matter both of which are designed to block puncture holes by filling rather than “glue” the rim and tire to one another.
