Personally I like to stay clear of hashes of hashes, particularly where the second hash contains common keys (e.g. the column names of a table).

At the end of the day arrays are probably not that much faster than hashes.. but hashes sure do take up a lot of extra memory with those verbose keys.. particularly if the verbose keys are containing redundant information.
