All a matter of choices

I've just been converting some high speed (ISO 1600) photos taken last night at the carneval in Bellinzona. The differences between Adobe Camera Raw and Olympus Studio are really quite striking. I think I prefer the colour from Olympus Studio - I think it is more accurate. But ACR has more punch. Finally you end up wondering which is closest to the "truth" ...
Converted with Adobe Camera Raw:
Converted with Olympus Studio (noise reduction ON, High Speed):
Noise reduction is also interesting. I thought, from screen previews, that ACR was better. But on review in Photoshop, I found that Studio seems to do a better job - it reduces colour noise better, without losing so much detail. Of course it is not so easy to do a straight comparison, as the two programs have different controls. But for batch processing on this evidence I might tend to prefer Studio. But there are plenty more parameters to fiddle with yet.
100% zoom, ACR:
100% zoom, Studio:
One strange thing I discovered in ACR (to me anyway) is that the Preview button toggles between the current setting and the "initial" settings. Well, obviously it has to start somewhere, but it might be nicer if it used a "flat" setting as the reference, with all settings zero or neutral.

ACR has the big advantages of histogram display and responsiveness. The live over / under exposure warnings you can get when dragging the exposure / shadow sliders are really good. So for exposure control, no problem. ACR wins. Olympus Studio just has a single slider for increasing or reducing exposure, and, incredibly, no histogram in the RAW converter.
On the other hand, the noise reduction algorithms in Studio seem more sophisticated. ACR insists on applying colour noise reduction by default, as I've said before, but both experiment and general consensus indicate that except at ISO 3200 the E1 doesn't suffer much from this kind of noise.
What is also nice in Studio is the (presumably) intelligent lens distortion correction. There's nothing like this in ACR. It does have vignetting and chromatic aberration correction, but, again, these are not known as E1 faults.
However, ACR does have one big advantage, at least according to
