IPhone users: how well does the vpn work?

IPhone users - How well does the VPN functionality on the iPhones work? Is it a lot better than Android?

I had no issues using it, my home router allows for incoming VPN connections and I use this from my iPhone to access securely the internet when I use an open Wi-Fi, reconnects by itself smoothly when swapping from Wi-Fi back to cellular coverage. No complaints, VPN status icon in the status bar when active.

There's an OpenVPN app in the app store, integrates more or less smoothly OpenVPN support in your phone if you use OpenVPN already (only tun, no tap)

The VPN works well on my iPhone.
