My first Spyderco was the Paramilitary, I also have the CTS-XHP and S30V Manix 2 springs, Love all three knives, the para and manix are my favorite 3 folders I have and top 2 favorite current spyderco models. In hand the Manix feels a little sturdier because of the stouter liners, thicker blade profile and weight. Although the compression lock is probably my favorite lock out there even over the AXIS and CBBL lock of benchmade and on the Manix. Although those are my next favorites. Although the blade of the manix isn't much longer than the para it seems quite a bit bigger just because of the shape probably. The para is lighter and easier to EDC and the FFG will be a better slicer than the Saber grind and has MY favorite lock (some don't like it at all). The manix is heavier and sturdier feeling with my second favorite lock, thicker blade stock, all the way through the tip, and a bigger overall blade, I think I like the blade shape a little better as well. Good luck with your choice, both are excellent, the para2 as already mentioned looks extremely promising as well.
