In principle, any over-unity fusion would be good. But the prospective implementation costs for each are part of the package, and it isn’t even really a contest. FF has by far the best costing prospects.
It seems unfair to deprive FF and LPP of a dedicated cheering section to try and be a Big Tent for fusion, though! It’s not as though the others don’t have their own followers and promoters. Encouraging communication and co-operation is realistic; attempting to be all things to all parties is not.
Underlying all is the implicit/explicit competition for resources (mostly but not solely money, of course) for research and development. It’s pretty hard to fudge on that issue!
