What vmware version do you use: server, esxi?? What type of applications do you run under these vms??
How mature is your organization? How big will this get?
Why ? I thought about technical comparison of both approaches. Then having it you can see if this particular approach is suitable for you.

Which type of comporasion do you need??
Well, it seems that Best Practise would be better name for what I am looking for :-)
Best practice?? I don't think so ... You need to choose between two different virtualization products. And the principal point here is: your budget and your SLA.
- How many vms supports each one??
I am looking for information like below:
- when you use KVM using more KVM VMs then X is not advisable since ...
- How many nodes can install inside a cluster??
- How many ram can I assign to a vm??
As many as appliaction need.
It depends. There isn't a magic formula to accomplish this.
- Hard and soft limits on both platforms???
- What type of storage is supported on both platforms???
In general when you have many OS-es (CentOS) you face following problems:
- how to keep up with package updates ?
Like in physical world...
- how about security - is it easier to manage many CentOS-es or just one with many KVMs ?
It's the same. But security is another beast.... You can't control your virtual infrastructure like you do in physical world ... Virtual infrastructures are more vulnerable ...
- how to keep up with application maintenance (mysql, postgresql, apache, dns, etc) ?
Same as you do in physical world.
Which approach would be better/easier ?
Between what?? vmware and kvm?? In your case, KVM is the best option if all vms are centos.
