I would vote for California. San Francisco - Anaheim/LA. Downtown to downtown in less than three hours for a presently projected O/W fare of $100 - $120. Fantastic compared to the miserable flying alternatives. This will be true HSR - 220mph.
I voted for CA as well. If you add the $2.3B to the matching funds required and the $10B that was passed by the voters in 2006, you get nearly $15B which is about enough to get all the way in construction which CA HSR is now estimating may start late this year. In addition the CA corridor is second busiest in the country and nearly maxed out in air traffic.
I voted for California not because I'm expecting a completed route soon, but because the first segment likely to be completed will likely be the Central Valley portion, IMBY.
Getting it to L.A. or San Francisco requires expensive viaducts and tunnels, and those are longer-term.
Here in the Central Valley most of the ROW is going to be adjacent to the existing UP line, we've been told.
Modesto to Bakersfield in 90 minutes, woo-hoo!
