There’s no one-size-fits-all protocol, but for most people WireGuard delivers the best mix of speed, stability, and simplicity.

TL;DR quick picks

Default for most users: WireGuard → modern crypto, low latency, seamless roaming on mobile.
When networks are hostile to UDP or do TLS inspection: OpenVPN (TCP/443) blends in as HTTPS.
If your OS favors it and you want native profiles: IKEv2/IPsec is rock-solid on iOS/macOS/Windows.

For everyday browsing, streaming, and travel, start with WireGuard. If a hotel/campus blocks it, fall back to OpenVPN-TCP/443; if you love native OS profiles, try IKEv2.

Why WireGuard wins for everyday use

Modern design, lean code
WireGuard’s small codebase is easier to audit and typically yields fewer implementation bugs than legacy stacks.

Fast and battery-friendly
Lower overhead means snappier page loads and lower latency—especially noticeable on mobile and gaming.

Seamless handoffs while traveling
WireGuard is built for roaming (Wi-Fi ⇄ 4G/5G), so connections recover quickly as you move.

Straightforward configuration
Fewer knobs = fewer ways to misconfigure. That simplicity helps providers deliver consistent performance.

When OpenVPN still shines

Compatibility and censorship resistance
OpenVPN can run over UDP for speed or TCP/443 to masquerade as regular HTTPS. On restrictive networks, this often punches through where UDP is blocked.

Ecosystem depth
It remains widely supported across routers, NAS devices, and older platforms—handy for edge cases.

Trade-offs: more overhead than WireGuard; complex configs can be error-prone.

Where IKEv2/IPsec fits

Native on iOS/macOS/Windows
If you prefer OS-level profiles, IKEv2 is stable and quick to reconnect, making it great for mobile users.

Caveats
Some NATs/hotel firewalls dislike IPsec, and obfuscation typically requires extra tooling.
Spec: RFC 7296 → https://www.rfc-editor.org/rfc/rfc7296

How to choose (practical scenarios)

I want the best speed and smooth browsing/streaming

Start with WireGuard. If a network blocks it, try OpenVPN-UDP, then OpenVPN-TCP/443.

I roam between Wi-Fi and cellular all day

WireGuard (or IKEv2 if you love native profiles). WireGuard usually wins on latency.

I’m on restrictive or monitored networks

Use OpenVPN-TCP/443 to blend with HTTPS. If your provider offers obfuscation (e.g., TLS camouflage), enable it.

I need widest device compatibility (routers, old gear)

OpenVPN still has the broadest support.

Performance & reliability tips

Pick a nearby server to reduce RTT.
For flaky links, adjust MTU (some apps let you try 1280–1420).
Turn on kill switch + auto-connect to avoid leaks during drops.
Benchmark fairly: same server, multiple runs, back-to-back protocol tests.

Security & privacy notes

WireGuard, OpenVPN, and IKEv2 are all secure when properly implemented.
Trust the provider’s posture: independent audits, clear no-logs stance, private DNS, and sensible defaults.
Obfuscation (to bypass blocks) is a separate layer—use it only when needed.

Bottom line

Use WireGuard as your everyday default: it’s faster, simpler, and more mobile-friendly. Keep OpenVPN-TCP/443 in your back pocket for restrictive networks, and consider IKEv2 if you want native OS profiles. The best protocol is the one that keeps you private, fast, and stable—on the networks you actually use.
