World's Premium Monofilament Fishing Line vs Camping World Ugly Stik Complete Spinning Kit: which is safer?

Where these two actually differ

• We flag Nylon polymer leaching (monomers, plasticizers), UV-absorber additives, Fragmentation and microplastic shedding over time and Allergic sensitivity to nylon dust or residual processing chemicals on the KastKing and not on the Ugly Stik.
• We flag Fiberglass splinters from rod degradation, Plastic reel microplastics from wear and Bacterial growth in reel housing if wet and unmaintained on the Ugly Stik and not on the KastKing.
• The KastKing is Monofilament nylon fishing line where the Ugly Stik is Fiberglass rod, plastic reel, rubber grip, which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
