It would be great if there was a chess variant that was better than current chess. But Chess960 only solves one problem, and that is the problem of needing to learn chess openings - a problem that gets bigger and bigger the better and better chess player you are.
If Chess960 had been Chess1440 from the start (which is the same as Chess960 but there is no castling rule) then the rules of this variant would have been simpler and the game might have been even more interesting than it is now.
The current castling rules for Chess960 make this variant explicitly a variant for chess enthusiasts and not for the general public, who would take it as the better variant.
The game looks great, but remember, Bobby Fischer was a rabid antisemite, and I would never play any game named after him.
