RSE I found it very difficult to get colours right and controls introduced noise unless used with extreme care. Capture One I found it very good for colour, sharpness and noise but the file handling is not so good. PS is in the middle of the two and given it's ease with introducing RAW images as smart objects in CS2 I think it has the advantage.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
