Getting around Generator

I'm looking to buy Generator Enterprise Edition for my company, but with all the stuff you can do with just ActionScripting's loadVariables command in conjunction with a dynamic web page, I'm wondering if Generator is really necessary.

What can Generator do that cannot be done with ActionScripting?

Can you pull dynamic graphics from the web or a database without the use of Generator?

Can Generator really handle a much bigger load when dynamically creating content?

Thanks in advance!
