Not sure it's that deep honestly. Most garage tools are gonna surface rust if you let them sit in puddles, forged or not. I've got a no-name set from Harbor Freight that's been in a cardboard box in my damp basement for like 6 years and they're still fine after a quick wipe with an oily rag. Maybe it's more about how much you use them and where you keep them than the brand. Your mileage may vary though.
