Jumping right in, no fluff needed. WireGuard is the new kid on the block promising lighter code, faster speeds, and simpler configs. I've seen some solid speed tests on it, especially on mobile. OpenVPN, still the heavyweight, mostly due to its maturity and flexibility. It's solid on security but can be a bit heavy on resource use. IKEv2 is kind of the middle ground, fast on some devices, decent security, but its dependency on IPsec makes it a little more complex to set up and troubleshoot. Here's the rub though speed isn't just about raw numbers, it's about how it performs under load and in real-world scenarios. Security-wise, OpenVPN's got the longest track record, but WireGuard's code audit progress and adoption look promising. IKEv2 is generally secure, but it's more vulnerable if your device's implementation isn't rock solid. So, for streaming or torrenting, WireGuard seems the best bet right now, if the provider has solid support. But check the fine print on your chosen VPN, especially about the encryption standards and key management. Bottom line if speed and simplicity matter most, WireGuard is pushing ahead. For proven security and flexibility, OpenVPN still rules. IKEv2 might be good for mobile setups where connection stability and battery efficiency matter. Just don't get lazy on the configurations, especially on IKEv2, because a weak setup can open vulnerabilities.
