Plastic turns brittle in time and can be a right pig to fix if you get a leak.

Copper can corrode, especially if the flux residue is not cleaned off after soldering. Much easier to repair and modify.

All good quality plastic piping have a 25 year guarantee. I don't see how plastic can be harder to repair than copper. No need for hot works, solder, pipe benders, less joins and bends required. Less risk of setting premises on fire. Only copper required will be at boiler side first 1-1.5m and radiator tails.
