To be honest, I have no clue, I've never used GHDL. For Yosys I'm not too sure either but their README indicates that it has mostly complete Verilog-2005 support, and a few features from SystemVerilog too.
It also seems like YosysHQ's prepackaged OSS CAD Suite ships with the GHDL plugin, making installation a breeze compared to building from source (just extract the suite and add to PATH).
