Matthew J Moynihan's response to a Quora question [1] points out there are general fusion physics and engineering problems regardless of the reactor design that remain open questions starved for data points. If anything going by his response, it isn't the type of reactor that matters now as much as getting more research data. We don't have a spare trillion to throw into fusion research, but we certainly do have enough tens of trillions to prop up all the central banks in the world [2].
