I can not comment about stability because i have not any p5xx with aix
5.3 in my hands. But i can talk about flexability.

First of all. You have to have a need for micro partitioning like
server consolidation, running different kind of apps not in the same
environment, need for batch-jobs a.s.o.
The most advantage with micro-partiting is that your idl-time goes
below 10% because the ability from the VM to share process-power by a
1/100 of a cpu, 16 MB ( just from memory ) chunks of memory and also
virtulize disk and network i/o

A very very simple example:
20 2way Servers before with each has 2GB-Memory, 2*GB-Adapter,
2*FibreAdapter
which made up:
40 CPU
80 GB Memory
40 GB Eth. Adapter
40 GB Fibre Adapter

and a average load of 25%

Now you have a p570 with
16 CPU
64 GB
6 GB Eth. Adapter
6 GB Fibre Adapter

using virtuell i/o and micro-partioning
and a average load of 90%

I would wait not even one second to install and customize such a
machine ;-)
So go for it.

Lets assume a simple environment

You have need for:
Webservice 24*7
Batch Processing nightly
