It's been said that plastic pipe is easier to work with. I think this has been said by someone who hasn't had to repair it.
This leak was showing up a few feet away from the pipe through a crack in the driveway. Some-other-plumbing-company wanted to replace the whole line for a lot of money, but the building owner (commercial place) called us for a second opinion. It took him a second to hire us and we completed the repair in less time it took that-other-company to write their estimate.
