Apparently everybody is developing/offering their own blockchains: IBM, Oracle, Visa, MasterCard,...
Is there any kind of comparison or analysis between the existing(available and under development) private chains and information on actual applications?

I guess the majority of those technologies use the blockchain concept but do not have the same goal of bitcoin. For instance, If I'm trying to solve a supply chain transparency of product X, I would use hyperledger, not a permissionless public blockchain and Bitcoin script ( https://en.bitcoin.it/wiki/Script )

When we are talking about company-owned/patented blockchains we are mainly talking their versions of it involving either the system of their business or even a product of it. Mostly their blockchains don't have a cryptocurrency or payment transaction involved but for other things like Walmart planning to have a medical record based blockchain or Coca-cola developing a blockchain that can "end" forced labor. Still the process of storing and keeping the records would be closely similar to what the original blockchain has to offer.

yep, this is the way it goes and I'm not really talking about crypto, but rather of the actual use cases of the underlying technology and its adoption.
It seems that we are in a point where adoption cycle has started and better understanding of fundamentals can be deduced from it.

Ideally I'd like to have better understanding where "public" part may play a critical role. What are the actual applications that are in real demand and what feature sets are needed.
I mean it's obvious that in our age of data it can be a real need to have sources of information that are trusted(immutable, decentralized, allowing various degrees of privacy, etc), accessible, scalable, etc...

So my question remains is there any adoption analysis /comparison between existing blockchain tech, actually no matter private or public.
Any suggestions for information sources/materials on the subject? Anyone?
