I have both stainless and a "pinto" style, both built by the same guy. Have had no problem with either being affected by rust and my carbon steel frame has been shot during a hurricane in Jackson, MS. Regular cleaning and maintenance will keep either running strong for years. As Palmetto SS stated it is a personal preference thing. Sometimes the all stainless gun will really reflect the sun and I pretty much smoke the entire bacl of the frame to cut the glare while the blued frame doesn't have that issue.
