Britain is also uniquely bad at government contracting. As we can see in detailed studies about cost of transport engineering.
As with everything things can be done well and can be done badly. And it really depends on this exact situation and the exact contract.
And both well done likely not that different in cost and other factors need to be included.
In terms of transparency having an isolated outside of government structure, you can potentially be more transparent as you can get detailed contracts down to item levels and have all those things be public. This is done in other nations when it comes to transport projects. But it of course depends on the government writing the contract to demand the level of transparency.
