Matt, They do look very similar, I think the Rocrding KIng is a better spec, the Sigma is a ply back and sides has no body binding or rear centre seam, but otherwise very similar. It fingerpicks really well but wouldn't say it strums so good. I have read that Mahogany is a stiffer wood than Spruce so punches the sound out quicker and louder so that probably explains with it fingerpicks better than it strums. I think it is extremely good value for money and I wouldn't be without it now. Nice discussing guitars with you, regards, nigel
