I like a lot of the presets. I always change some of the stuff, but presets help get you there sooner. As far as amp/cab stuff, I usually edit that stuff myself, but for some of the effects stuff, some of these presets do things that I never thought of. The use of modifiers, parallel paths, etc. I would say that there is some value in commercial presets, especially if it has different effects settings that I normally wouldn't think to use. From the Gift of Tone for Axe III, the Devin Townsend preset with the way the wah is setup is something that I would not think of or design myself.
It depends on what your after. For amp/cab stuff, I think that the looper can help you dial in tones that you normally wouldn't. It allows you to make adjustments without playing. I have found that this is the most effective way to get good tones fast. I usually delete the looper block once I get things dialed in, but it is very helpful in setting EQ and most importantly mic placement with Dyna Cabs.
