I cannot say whether Golen is better established. The projects that are able to roll out adoption at a greater pace would be the ones to scale their growth. 

As of now, I know DeepCloud has clients for DeepTransfer. That's a strong start. If their AI can seamlessly allocate resources, then we're off to a new era of cloud computing. A good UX during the user shift is off essence. 

You're welcome to detail Golem's development as I have only kept up with it on a topical level.
