The one that surprised me the most was my 1.5-5x20 Leupold with the Heavy Duplex. I put it against my 30 mm tube Zeiss & Swarovski 42 mm objective Euro scopes and that Leupold Heavy Duplex stood out well past legal light. The standard Duplex reticle in the Leupold 2.5-8x36 disappears in low light much faster.
