Asbestos can take 10-80 years to cause cancer based on a cursory Google search while plastics are capable of causing a decline in fertility rates for at least two generations as well as begin to immediately interfere with hormone levels/production.
It took decades to understand asbestos was bad as it is and even then it took direct exposure (generally with you working with the stuff). Plastic is building up in the environment daily, and the levels have only really start to increase.
Plastic is also effectively forever, there is no practical plastic abatement like there is with asbestos. One great way of dealing with asbestos removal is keeping it damp, microplastics though are just going to spread with water. Microplastics are in the air and water, it's effectively falling like snow from the sky which is documented in the NatGeo article I linked.
Concentrations of microplastics is only going to go up as more and more of the plastic we've created starts to break down into smaller and smaller pieces. When you get small enough, like nano-scale, particles can get extremely dangerous as they can cross the cell membrane.
Plastic pollution is likely going to be far worse than asbestos and for incredibly more species.
