I really don't think you can say one forecast or the other is any more accurate at this timeframe out.
By the sheer nature of tropical revolving storms, you can't accurately predict their path with any certainty more than a few (2 or 3) days out. That is the whole thing with them re-curving - it is not predictable.
When two or more separate forecasts starting agreeing on a track, that is when the forecasts start becoming more reliable.
That said, the in-house Predict Wind forecasts aren't good for cyclones. My logic is that those forecasts were developed and fine tuned for 'mid range' wind, i.e. good sailing breezes. The European and US forecasts are more focused around 'public good' such as predicting server weather events. Already we are seeing those forecasts with more plausible tracks than the in-house Predict Wind ones.
