Timber can suit older stone fronts when profiles, paint and maintenance are accepted as part of the deal. It can be repaired in places; it also needs looking after through wet Fife winters. UPVC reduces that maintenance load and is common on later houses in Abbeyview, Touch and Duloch, where openings are often more regular.
On Abbey-area elevations, colour, sightlines and how the frame meets the stone matter as much as the material label. A white frame that fills the reveal badly will look wrong whether it is timber or plastic. The survey is where those proportions get checked — not a catalogue page.
