I ride with the R version. I bought the Sport version too, for mounting on a folder, but have not put it on yet. Everybody, at least in the US, going for the Sport does not surprise me - standard tendency of going for some easily quantifiable performance. In my experience, at bicycle speeds, it is far more important to see well nearby than maximize the far-away region, so it did not take me long to decide.

Anyway, Cyo R is excellent nearby and is better than any other lamp I have used before (Bisy, Lumotec) far away. Far away traffic signs are illuminated comparably well to low-beam car headlights. Otherwise far-away illumination is needed, in my opinion, in steep descents. I have one, where I ride fast within a narrow passage, even in winter, and I feel no urge for a better illumination there.

I have got the Sport version for a folder, because the low mounting will cut the beam in such a way that an OK nearby illumination will emerge even for a beam optimized for farther distances.
