It's hard to explain in only a few words.

Advantages of XFA:
- it's XML.
- it's new.
- it offers some flexibility.

Disadvantages of XFA:
- it's XML.
- it's new: not many tools support it
- it's not really PDF

Advantages of AcroForms:
- it's PDF.
- it has been around for a while.
- iText knows how to manipulate AcroForms pretty well,
   and so do some other tools
- you know what you'll get: all fields are fixed

Disadvantages of AcroForms:
- the way Adobe Acrobat and Reader create appearances
   has been changing in between versions, so you don't
   always get exactly what you expect (this is an
   amendment of the fourth advantage).
