But it's faster, right?🙄

(please get the sarcasm and don't drop a diatribe on me thanks)

Some benchmark show that 64-bit kernel is actually faster than the 32-bit kernel with Snow Leopard.

Not sure if this is true in Lion though.
 
You'd need at least 8GB memory and a crisp eye on fractional gains for this to be true. On Lion it most likely is faster as they spent more time developing in 64-bit kernel rather than 32-bit kernel. I know 64-bit kernel drains my battery more😉 Rest is placebo.
