Pimcore Vs PyroCMS

In the future, the company I work with atm would like to stop in various framework / cms systems and move forward with only one of all future customers.

For this purpose, I prepared a list of options, and it was reduced to Pimcore and PyroCMS. I am a CI developer, so Pyro wins for me, but the guys who will develop custom modules are more convenient in Zend. I found this: What are the benefits (dis) of the benefits of pimcore? and found it quite useful.

So, I'm curious to know the thoughts about the two systems based on the following criteria:

• Reskinning potential (foreground themes, etc.).
• User module. Building modules are very lightweight in Pyro and intuitive (if you know CI) .. Is Pimcore just as easy for Zend gurus? Also, just buying / downloading existing modules that are more prolific?
• Multi-page use of the site (can I install the administrator user from site A to see only the content of the site?)

Documents and commercials are great for both sites, but any helpful tips here will be helpful.

I think we could just use the Zend library in Pyro (as you can do with CI yourself). Does anyone think there will be a headache to use?
