The Marmalada HD have shocking linings, my wife returned a pair very quickly and got a free upgrade but we did hear there was quality issues with that model. I got through 2 pairs of Hanwag Makra's under guarantee and found them extremely comfortable / easy to climb in but shocking durability.
The Scarpa SL's are an old style clumpy boot which has it's place but doesn't climb anywhere near as well as the Hanwag Makra. I'd say it depends how waterproff and how long you will need them to last verses how light and well they climb. Personally I went with the Scarpa Mescalito mid as a light scrambler but the Bestard Breithorn as a clumpy heavyweight to cover both uses.
The layout finacially is much more but it means the boots will last longer and I have boots that are activity specific. Depends how much £££ you have going spare to throw as footware but personally I do prefer specific tools for specific tasks.
