From looks, I like the anonymous array one too because brackets are...well, sexy. But for those interested in micro optimization, the benchmarks say that the list is faster.

Benchmark: running anon, list for at least 5 CPU seconds...
      anon:  6 wallclock secs ( 5.25 usr +  0.01 sys = 5.26 CPU) @ 875
+11.49/s (n=460119)
      list:  4 wallclock secs ( 5.29 usr +  0.00 sys = 5.29 CPU) @ 121
+428.51/s (n=642243)
         Rate anon list
anon  87511/s   -- -28%
list 121429/s  39%   --

Those are the benchmarks from your script above. Regardless how you vary the length of the string, the ratio held around the same. Hope this helps.
