Whether are not it pleases you.
I use Canon, Nikon,Leica and Pentax...and I can tell you here and now that as far as this issue is concerned switching manufacturer won't make any difference to the outcome, and in all probability make your problems worse.
When flash is the sole light source used to illuminate a subject, the synch speed has very little to do with freezing motion. Because the illumination from the flash is in some cases thousands of times shorter then the synch speed of any camera.
the only time where the synch speed can become an issue is when long lenses are being hand held, but I consider it poor technique for a photographer to be hand holding a 400mm f/2.8 - sure, it can be done but to get the best results from any telephoto lens the use of a
sturdy support is highly recommended.

Have you actually watched the shutter of the LX5 in action? It follows exactly the same sequence that a leaf shutter does. All I know is that there is a leaf shutter mechanism in there, and think about it the LX5 is a premium compact, what makes you so sure it wouldn't have a real shutter in it? Also when the sensor's shutter is in use for video recording you can get some pretty bad blooming and streaking effects on bright highlights which are known side effects of the sensor design compromises involved that enable the use of rolling shutters with a CCD sensor....but these artefacts aren't present during still image capture.
