Honestly, finding real-world scenarios where libvpx can deliver better quality @ bitrate @ perf than x264 is a challenge, although I suspect that's primarily due to x264's massively greater psychovisual tuning and perf optimization efforts, not differences in the bitstream standards.

I think the same could be said for HEVC too compared to AVC.
I remember the days when x265 was claiming 50% more compression for the same quality compared to x264, but you have to dig too much to find such a case, if any.
