Samer, at a high level, I think both could do a solid job in a shopping center.
Can you be more specific about what technology or problems you want solved? For example, Axis has far more options for PTZs, so if you plan to deploy a lot of PTZs, Axis is likely better.
On the other hand, if the system is large, Axis' VMS, ACS is probably not a good fit, so either all Avigilon or Axis + a third party VMS would be better.
If you can explain more about what the shopping center needs or wants, this would enable us to provide you better feedback.

One of the other things I would take a look at is local support, Axis is open so pretty much any security company can get support; Avigilon would get a little more difficult if you don't have dealers in the areas you're trying to do the upgrade (assuming it isn't a single shopping center).
Both definitely have their pro's and con's; I would typically suggest Axis but given unique circumstances there are definitely times that Avigilon is a better fit. Are you planning on using a single manufacturer end-to-end or using a VMS? If so, then that may allow you to not have to pick between the two
Axis does have a nice selection of PTZ cameras which do work well with Avigilon's ACC software so you can mix cameras if you need/want to.
I am under the impression that you will get more out of your storage and servers with Axis zipstream technology.
