The wall charger is usually the guaranteed way to charge the fastest.
However, assuming you directly connect your BlackBerry to a fully powered desktop computer (bypass all USB hubs, unless they're good powered ones), and you've got all drivers installed, and the lightning bolt icon, then the desktop computer should charge equally as fast. At least, in theory.
