Wood or metal?
I vote "other".
The two best cameras I have or have had through my hands are the Gandolfi Variant (MDF) and the Carbon Infinity (carbon fiber).
Get a wood, metal or "other" camera not because of the material, but because it has the functions you want at a price you can afford.
Oh - the Gandolfi Traditional is wood, and a great camera too! Possibly my favourite camera, but I haven't tried that in 4x5" - only 5x7" and 8x10".
