Consider it a matter of curiosity, not any sort of statement of quality or allegiance--which retro-clone (OSRIC, Swords & Wizardry, Labyrinth Lord, etc.) is getting the most play or attention right now?
It's tough to gauge, because online discussion doesn't always hinge on actual play, but I find myself wondering if we'll get to a point where one is standing head and shoulders above the others in terms of support.
James Raggi seemed to feel the OSRIC was getting left behind somewhat. I can't say as how I've noticed, but then again, I felt like Swords & Wizardry had a pretty good push going there for a while.
Again, it doesn't really matter, aside from wondering how things will pan out, and if we'll see one of those entries make a bigger jump than the others. They're all great efforts, and I'd be proud of any of them. Personally, I like them all and currently run Castles & Crusades, which is why I love system-lite products that can easily be used with any legacy-style game. No reason to cut up the pie any more than it already is.
