Docker compose is certainly enough for personal use, but if you ever want your apps to be available during update process (on docker compose you'll have to shut down your app container before you can update it), it's very easy to setup a basic blue/green deployment using the readiness probe option in kubernetes. Also, kubernetes load balancer is pretty easy to setup and plays well with multiple services and letsencrypt. On docker compose, I'll have to either use nginx and update it everytime I add more apps or use something like traefik if I want a load balancer that can read configuration from app's label. On kubernetes you simply specify several lines of ingress definition in your yaml file, which is not too complex for a typical app.
