For durability and an almost maintenance free ownership, stainless and composite beat blued and wood hands down.
My stainless Remington 700 is 18 years old, and the most discoloration on it is some marking on the nickel scope from taping camo on it. It's usually shot for zero, used deer hunting, and the stored in it's case uncleaned.
ALL the blued steel guns I have are rusted and need constant protection even stored in the house. They cannot be left in the basement or any room that experiences high summertime humidity, or I will see more speckling the next season no matter what. There is no gun oil that will protect them unused for years of storage. Only a climate controlled dehumidified enclosed safe will do that - which is exactly what an arms room is in the military, or at Cabelas.
Carbon steel rusts, but it's cheap, and as long as consumers keep buying on price, not quality materials, that's exactly what they should expect.
My last purchase was a barrel completely nitrided with matched bolt and bolt carrier, I won't clean it either. It won't rust, just like the knives I've had with that treatment for over ten years of daily carry.
Carbon steel is planned obsolescence and high maintenance.
