When setting up VPN for clients what VPN protocols do you configure?

I normally setup both L2TP with IPSEC and SSL (for backup when firewalls cause issues) both in a configured Draytek Smart Client config which I send them. Just wondering what others setup and how they deploy them?

WireGuard, I just bought was on those really cheap GL.iNet routers to handle it, works really well.. I hope it's secure.... :?
