If you prefer to use OpenVPN exclusively, use UDP rather than TCP to get the best speeds.
Just be aware that - though their security appears to be solid - these protocols haven't been as thoroughly tested in the wild as OpenVPN, so they shouldn't be your first choice for critical VPN use. Switching to one of these other protocols, if offered by your VPN provider, can yield you faster connection speeds through your VPN. And some have even developed proprietary VPN protocols like ExpressVPN's Lightway and NordVPN's NordLynx that claim to offer the best of both worlds. More VPN providers are now offering newer VPN protocols like IKEv2 and WireGuard that promise faster speeds alongside excellent security. It is the most battle-tested protocol, and it offers a nice combination of speed, stability and security - which is why many VPNs use OpenVPN as their default protocol. Today, the gold standard VPN protocol is OpenVPN.
