ghci-ng VS hie-core

I've only dabbled with GHCI. I've used it as a standalone REPL for trying out small things, the same way I'd use a Python or Javascript REPL. I haven't used the REPL /the/ developer interface to the program. In Clojure, I would (1) start a REPL server, (2) connect to it from my editor, and (3) send expressions to it. I didn't develop Haskell that way, though I think it was possible with Intero[1].

Within the Clojure community, there's a perception that the Clojure REPL is one of its strongest selling points[2].

Are you using the REPL actively when developing?

A challenger to Solidity? Never heard of anyone else using this before.

How does it make sense to say that a system is both a blockchain and not a blockchain at the same time? Is enterprise blockchain (also called DLT) censorship resistant? What are the main challenges of implementing enterprise blockchain in real life, and how can Daml (Digital Asset’s open source smart contract language and platform) help tackle the challenges? We’ll look at those questions and others in this post.

I'm looking for Daml (smart contracts) developers to build out smart contract templates for a wallet application will be used to mint / swap / send digital asset.

It's extremely easy to get started. All you need to do is describe the behavior of your application in an easy to read and write smart-contract language, and let Daml take care of infrastructure and integrations. You can take a look here https://daml.com/

If the goal is to create a supply chain management system, and get experience in writing smart contracts, I would suggest checking out Daml (https://daml.com/). Daml is a smart contract language which can be later deployed onto Hyerpledger Fabric if you wish, or other blockchains.
