Pop-up window or modal box?

Question

I'm designing a mission-critical web application and I was wondering if it is best to have users enter in data via browser pop-up windows or javascript modal boxes?

The absolutely critical aspect is that data must save correctly through HTML forms.

I would tend towards self-made, modal boxes for a number of reasons: Input elements can be styled, can be made more convenient, and prompt() dialogs tend to get eaten by IE's popup blocker.

However, the method of input you choose is not essential: The correct encoding of the page containing the input form, the database connection and the database tables storing the data is what's really important.
