14 megapixels is the native size of the pictures the FZ100 produces. The way I interpret the manual is that it will not imprint photos larger than 3 megapixels.
Regarding the Canon, it has gotten good reviews. From test images I have seen, the Canon produces slightly better photos than the Panasonic. I do not know how extensively you tried the SX30 IS, or where, but it sounds like either the white balance was not set correctly, or you prefer the default JPEG "signature" of the FZ100. Both cameras can be modified for color and white balance.
