I have done significant development work using hyperledger platform and aside from the fact that private blockchains are essentially pointless, this is (or at least recently was) pretty unusable, with very bad tooling and support.

I took a course on this whole thing on edx and I walked away with the same feeling.

  Out of all the Ethereum contracts people have come up with so far, I still haven't found anything truly useful. Closest thing is just the ability to create "stock" like entities.

    Fabric isn't Ethereum-based. It's the next most active smart contract platform, but way behind in developer interest.

Same. Admittedly, my work with it was with a fairly early version, but in spite of initial enthusiasm due to the fact that it is written in golang, I ended up very disappointed with a terrible developer experience. IBM's role in this mess didn't give me a whole lot of hope either.

Another comment from a technical perspective: Fabric doesn't even solve double spends. Say a logistics company uses Fabric to send diamonds to track (the prototypical blockchain business use case). Logistics Worker Alice goes to reserve Cargo Container C to ship her diamonds in. At the time, Logistics Worker Bob attempts to reserve Cargo Container C -- at the same time -- to ship his diamonds. This is a double spend (Company Cargo Container C -> Alice, Cargo Container C -> Bob). All Fabric does is takes both transactions, issues the txns to the "Orderer" and then both transactions get put into a block and pushed out to the nodes. The nodes are then left to deal with the bloat of having two transaction.
