Not the person you're asking, but result types pessimize code more, add register pressure, use more icache for largely dead code, etc. They're arguably noisier at the source level too.
That said, I've spent too much of my life chasing implicit control flow to accept exceptions. Heck, C++'s "noexcept" is a strong argument against exceptions all by itself.
