If you offered me mildly faster iteration OR mildly framerate at 10x compile I'd also choose the former. Iteration speed is king. But it's not either/or. If you offered me Debug/Release/Retail(LTCG)/SuperRetail(GPO) I'd love to have that fourth option. It doesn't have to come at the expensive of any other build configurations. Even if PGO takes 10 hours to compile. It's part of the overnight build. Great! There's no shortage of AAA games that have an overnight 12 hour process to build lightmaps for a single level. And that's using a build farm. But so far I've never heard a major, or even minor, PGO success story so it's all kinda moot. :)
