I've used Popeye because it comes shipped with k9s, which is the best k8s "dashboard" in my opinion. I really like it but it tends to bug out a bit on my terminal.
they put all the best to k9s: ncurses style of UI + vi style of key bindings
Our focus is on Google Cloud and Google Kubernetes Engine specifics but I love Popeye and K9S from derailed!
