Hi Sheeda Moti,
First of all, a warm welcome to CodeRanch!

I didn't read these study guides, so the only advice I can give is to have a look at the Amazon ratings and reviews. It will probably give you some idea about the books.
On Amazon you have also the Look Inside feature, so just read a few pages to see if you like the book (writing style, code snippets,...). The publisher of the book often provides on their website a free chapter which you can read to have a better idea of the study guide. So I suggest reading those as well. It will give you an idea about the writing style, the quality (do you encounter only a few typos or also important technical mistakes), the level of mock questions (if available), and so on.
Here you'll find the Sybex webpage (click on "
Read an Excerpt") and
here is the one for Oracle Press (but it seems there's no link to access/read a free chapter).
In my personal opinion, it's very important for technical books and study guides to have a publicly available errata overview as well. The official errata overview for the Sybex study guide can be found
here, I don't know if the Oracle Press study guide currently has such an overview.
And finally you could of course purchase both study guides as well. You could use one as your main study guide and use the other one as a complementary study guide.
Hope it helps!
Kind regards,
Roel
