Blacktail 2 Backpacking Tent vs Waterproof Tents with 3 Doors and Mesh Window, Camping Hiking Tents with 2000mm Waterproof for 5-6 Person for Camp: which is safer?

Where these two actually differ

• We flag Fluorinated DWR coating residues (PFOA/PFCs in historical treatments), Mold and bacterial growth in stored damp fabric and Heat sensitivity of DWR-coated nylon near fire or stove on the Big Agnes and not on the Kadyn.
• We flag Volatile Organic Compounds (VOCs) from waterproof coating off-gassing, Coating degradation and microplastic shedding and Mold and bacterial growth in fabric (maintenance failure) on the Kadyn and not on the Big Agnes.
• The Big Agnes is Nylon ripstop with DWR coating (type unspecified) where the Kadyn is Polyester tent fabric with waterproof coating, composition unspecified, 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.
