The sed version requires launching another process for sed to run in, and recording it's output. Not that it's that slow or that hard on resources, but it's slower than using commands that are already 'built-in' to the shell, and can run in the current process context.
The various forms of ${} substitution that exist in both ash and bash are very powerful, and can do most string manipulations if used in the right combination (see weblet for an example of lots of fancy tricks with shell paramter expansion :).
