I would value each of those companies' practical revenue potential as equal for now.
The operating costs themselves are eye watering, and the hardware is deprecating. So that has to be subtracted from revenue projections to get something like a real valuation.
I would invest in anthropic today, they seem to understand use cases better at the moment.
I also think LLMs are wildly over hyped, and they will be shunted to a niche in the next few years, essentially providing autocomplete or search for business tasks for the most part, with strong inroads on video analysis, automated translation, and other classic machine learning & neural net tasks.
