IT Consultant, KPMG VS Oracle VS Citrix Systems

Hi
Can someone provide your experience working for those companies as an IT consultant. I am a second year Master student in IT major. I have three offers on hand but hard for me to decide which one to take. (I am looking for the most potential growth in the future, especially I would like to develop my later career in Asia Pacific market). Here are the detail regard each positions regardless the compensation.

1. KPMG- IT enabled technology (SAP, Oracle, ERP solution) (70% public public
   sector project and 30% commercial sector)
   I don't have any finance/ accounting background. I am not sure if big 4 is a good
   choice for my future career since IT is not their major business. plus, I am not sure
   how big is their market in APAC in IT practice, Resume a big plus though.
   comments?

2. Oracle - functional consultant. (Public sector)
   Overall, I think Oracle is a great company with great products. Their APAC market
   has a great potential too. However, I will be joined in a public sector practice.
   People tend to avoid public sector. Not sure how easy to transfer to the project
   dealing with international though.

3. Citrix - Staff consultant (cloud solution, virtualization )
   New technology and great company review from Glassdoor. Only been Asia market
   for 5 years. Company is not as famous as other two.

Please let me know your thought for these three companies.

thanks!
