Makes for a suspicious comparison when both the two other options, have no features that hyper doesn't or is better. I understand that this comparison comes from you, and it's not easy being completely fair when doing a comparison, but I can't find anywhere anything against using Hyper or even any tradeoffs.
I'm not involved with Hyper/HyperContainer, I'm just a user and recently started contributing. I've had hyperd silently crashing once, and the API and tooling is a bit rough, but these things can be fixed. No complaints so far from a purely architectural viewpoint.
