I'm amazed that they both have solid earths. I don't think we have ever used solid earths in Australia. Stranded is much less likely to snap off at terminations. Stranded conductors are pretty much the norm here for everything except domestic light circuits. Much easier to work with and less likely to break.
If you use single insulated wires in conduit runs are they solid too? That's when you really notice how much easier stranded is to use.
