I've had the opposite path to Bruce - I've had a couple of years + on Impromptu and was asked to learn basic Crystal for some other applications. I found Crystal's approach to data access frustrating in comparison to crystal, but the control of formatting to be superior. I certainly agree that the existence of cognos script and the supplemental software makes automation better than Crystal, even with third party tools.
Note that, in my opinion, there is quite a change in the user experience between Crystal versions 8, 8.5, 9 and 10 (not seen 11). In comparison Imp 6 - Imp 7.3 is very similar; in effect just a few added features.
