Hi Mike,
Purely based on experience,

Pros,
Tubes and rectangular sections telescope,  sliding elements can move with good precision, rotate also
Load bearing movements can be handled with much smaller sizes than wood
Looks good in conjunction with darker timbers especially
Can be precision machined
Does not loosen/tighten up with "normal" temperature fluctuations
Annealing makes it easy to form

Cons,
Expensive
Lubrication neccessary for moving /sliding parts
Oxidises
Good soldering skills are needed, sloppy work shows  :-(

Plastic,
Pros,
Easily machined
Available in "lubricant" grade
Good for wheels, pulleys

Cons,
Doesn't look  good 

Regards,
Gus
