I've been using Nomad for about 5 months now, and couldn't disagree more. K8s is better documented, with far less glue, and far more new-hire developers are familiar with K8s compared to Nomad. Nomad-autoscaler alone is becoming a decent reason not to use Nomad. The number of abandoned issues on the various githubs is another. That Vault is a first-class citizen of K8s and a red-headed-stepchild of Nomad is another.
I do agree about Helm tho, I avoid it as much as possible.
Nomad is better for smaller teams and smaller companies with smaller problems than what k8s is for.
Helm is an abomination on top of it but that seems to be slowing down, thankfully.
