  5] Use of getChildHtml (‘childName’)
Use of getChildHtml (‘childName’) is recommended as this will cache block against direct use of block code in .phtml file:

getChildHtml function is used to get block code. We can not imagine that the block is defined in the layout file that
it will be rendered.

Either the toHtml() needs to explicitly render the child blocks, or the phtml assigned to the block must render the child
blocks via the getChildHtml() function.

You will want to be conscious of is the $useCache parameter.
If the $useCache parameter is true, Magento will check this internal property for an
existing generated output block before calling the toHtml method on the child block.
Class Name: Mage_Core_Block_Abstract
