It may be "better" and more optimized for a particular purpose: human memorization
It has a similar mnemonic strategy to other memorization techniques for numbers. Apparently, there's something special about the language processing of the brain that makes it easier to remember words than numeric sequences. Phone-number-to-words (vanity phone #) is another example.
For other tasks you mentioned such as mathematical calculation/comparison, or computer lookup in db indexes, the encoding is definitely not optimized for that. However, that's not its purpose.
