I see you've already purchased a knife in g10, but I'd still like to chime in. I don't own a Byrd knife myself, but I do own a g10 Spydie as well as an FRN handled model, and on the whole, I prefer FRN.
The look of g10 is quite attractive, that's a given. It looks and feels "high end," and it is. But it doesn't seem to be as wildly indestructible as FRN. G10, from my experiences, is softer than FRN. For example, the g10 handled Spyderco I own is the Ocelot, and from the factory, the clip orientation has the knife in the "tip down" position. I don't happen to like this position, so I unscrewed the clip to put it on the other side, in "tip up." After unscrewing the clip, I found that it had left a noticeable impression in the material. It had literally flattened the pattern. Not a huge problem, I cut a small piece of grip tape to fit over the mark, and it's worked perfectly to cover the blemish as well as provide extra grip. It even looks cool!
This really isn't a huge deal, but if you are a stickler about the condition of your tools (and toys!), the issue that I came across can be a bit disconcerting. FRN isn't quite as grippy, or stylish, but it's less expensive, tough as nails, and gets the job done just fine.
