Definitely the hap40 series from Seki, and now the rex45 series from Golden. I actually like the laminate lines on the hap40, and I've had great experiences sharpening hap40. I think the burnt orange color is slightly nicer on the seki models, but I'm super pleased with rex45, and the rex45 Manix 2 is one of my all-around favorite spydercos. I do regret missing the super blue seki models, though, and y'all know I've always coveted the caly 3 hap40 sprint run.
