I've got both and prefer the mosaic as it's one big map rather than hundreds of maps which can make thing akward at the map borders. Distance measuring is not as accurate with the mosaic though. The mosaic also comes with an oz landsat image.

The Mosaic has been "stiched" together so that instead of having all the seperate maps as seperate files that ozi loads automatically as you move around the country it is one huge map that is seemless. I personally purchased the mosaic after researching it alittle. What you will find is that the mosaic is not 100% accurate for measuring distances if you are spanning accross different maps, however when I measure distances I normally take the time to follow the highways with points anyway so IMHO they would be more accurate.
I have the seperate 50k maps of SW of WA and they are good in that they have height data and more details, however compared to the 250k mosiac they are a pain in the but, trying to plan a trip when you are jumping from map to map, trying to judge distances etc.
In short, I would go mosaic IMO. Much easier to use, works great. If you have some more detailed maps of the areas you normally go through, you can scan them in and calibrate them and then set Ozi to automatically find the most detailed map when driving along. That way you can plan with you mosaic and then when you actually get there, Ozi automatically zooms in to the more detailed map of where you are. Don't be scared with Ozi, it sounds very hard (even for computer nerds) but the software is so damn good once you have been playing with it for a few weeks, you'll find it just does everything for you.

the Mosaic is a huge advance as far as I'm concerned. With the sheets I kept opening maps and finding myself in the white surround. Crossing between maps was a drag. Now its all seemless and zoomable. I've used both with Ozi - would never revert to the single sheets.
