prepareForRender or pageBeginRender - which one should i use?

[Karthik N]

Hi,

I would like to do some initialization in a custom component that I'm
writing up.

I observe that I can do it in two ways:

1. Implement the PageBeginRenderListener and use pageBeginRender
2. Override prepareForRender

My question is: Which one should I use?

Thanks, Karthik
