Performance of Voice Assistant vs Rhasspy Junior

Hi all,
In a direct comparison, Rhasspy Junior seems to be much better in wake word detection and performance of executing the voice command.

Did anybody else experience this and how does this make sense and why have the more performant aspects of Rhasspy not made their way INTO voice assistant?
After all both are developed by the same person, I thought?

Nevertheless I love the whole voice assistant approach. Right now looking forward to the next Esphome update.

Thanks,
Merc
