In kubectx, inside a single session all the contexts will be available so switching back and forth won't be much safe. In kube-tmuxp every cluster will have its own kubeconfig file. Inside a tmux session there is no way to switch to a different kubernetes context. Contexts can be switched only by switching tmux sessions. Also tmux session switching is much easier than switching via command. For example: tmux-prefix + s lists all sessions and you can interactively switch between them.
