Generally, some of the advantages of the Panasonic TZ25 compared to boutique competitors include: it has way more more zoom (16x vs 3.1x), is slightly smaller (compact (105×58×33 mm) vs mid size (115×66×55 mm)), is thinner (1.3" vs 2.2"), is slightly lighter (208 g vs 393 g) and has a built-in flash.
However, on average it has a much narrower aperture (f/3.3 vs f/1.7), has a slightly lower resolution screen (460k dots vs 921k dots), has a marginally smaller sensor (1/2.3" 6.17x4.55mm vs four thirds 17.3x13mm), is older (january 2012 vs september 2014) and doesn't have a viewfinder (none vs digital).
