The first time I read this I misunderstood it's meaning. I now believe the parent is discussing the differences in usability not output. In which case I completely agree.

However I will say that for my company's use case a properly configured sphinx install produces better results than kaldi. However, getting to a point where you can say that was not an easy task.

Additionally, I actually believe that for most workloads that kaldi is likely better. Not ours though.
