Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony TX100V is significantly lighter (46g ) than the Panasonic ZS25 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-TX100V nor Panasonic Lumix DMC-ZS25 (Lumix DMC-TZ35) provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Sony TX100V's 3.50" LCD screen is slightly larger than Panasonic ZS25's 3" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
