Sure, I think that's valid. I just don't think Tokamak Energy's announcement is less of a stunt. They've both made progress on a well-defined but ultimately not-that-big piece of a big pie. Just different pieces. If the act of making big press pronouncements around incremental progress is a stunt, they all do it.

I hardly view "build a machine to understanding burning plasmas and steady-state tokamak operation" as a publicity stunt. These are hard machines to build in the best of conditions. The design of any power plant must be informed of results from machines like SPARC.
