When you put it that way, this is an unfair comparison and the downsides are more obvious. With GCC and Clang, I only pay for cross compilation if I need it, so for a fair comparison, the cross-compiler libraries should be installed for GCC and Clang. Also with GCC and Clang, I don't have to worry about a third party (the Zig team) incorporating bug and security fixes from upstream. And with GCC I get support for more platforms. If I have chosen to use cross-compilation, building for alternative architectures is just as easy as for Zig.
