samsung 860 vs 870

Thanks. mosasaurus vs megalodon size I'm not an advanced tech (which is why I came here for advice) but the simple observations that have me still wondering are that I read somewhere that the Pro line is more "durable" (lasts longer) than Evo and that the 860 Pro 1TB costs 3-4 times more than what the 870 Evo 1TB costs So, I'm thinking it's not only a matter of comparing
