I've read them both and prefer the Deshmukh/Malavia book though I also enjoyed the Wrox book. I think the first is just more thorough. The second however has more practical slant including a lengthy sample web application at end of book.
In deciding which to reread before taking
test, however I had no difficulty in choosing the Deshmukh book. And it's mock exams are much better than the Wrox book, at least in my opinion.
Hope this helps,
Ken
I hope to take exam next week so we'll see how useful they were;-)
