How the Three Clients Differ
v2rayN: Desktop Configuration and Routing
For Windows, macOS, or Linux, start with v2rayN. Its desktop interface brings server configurations, subscription groups, routing, and local listeners together. If you use several subscription sources, create groups by purpose and update them separately to keep temporary and long-term configurations organized. The wider desktop layout also makes it easier to review match conditions and outbound tags when adjusting V2Ray routing rules.
The Windows download page offers a desktop edition and a classic WPF edition. The desktop edition uses a newer cross-platform interface, while WPF retains the familiar classic Windows experience. They do not use different proxy protocols, and a newer-looking interface does not guarantee that a particular configuration will connect. Choose based on system requirements and workflow, then check the core and settings actually in use.
With v2rayN, the key is understanding the difference between the system proxy and routing. The system proxy tells apps that honor it where to send requests; routing determines which outbound handles requests that reach the core. These operate at different layers. Terminals and some standalone apps may ignore the system proxy, so a working browser does not mean every app is using the client. To handle more traffic, look into TUN and check for conflicts with permissions, DNS, and other virtual networking tools.

v2rayNG: Everyday Android Use and Per-App Proxying
For Android devices without a specific V2Fly compatibility requirement, choose v2rayNG. It primarily uses the Xray core. Typical steps are importing a subscription, updating configurations, selecting an entry, and starting the connection. On first launch, Android asks for VPN permission. This lets the client create a local virtual network interface through VpnService; it does not mean the client provides a shared remote service.
On mobile, troubleshooting often starts with system-level restrictions. If the connection drops after the screen has been off for a while, check battery optimization, background activity limits, and the manufacturer's app-sleep settings before changing protocol parameters. Another app using Android's VPN slot can also cause a traffic-handling conflict. First check which app controls the VPN connection, then review the client logs so a permission issue isn't mistaken for a broken configuration.
Per-app proxying lets you route traffic from selected apps only, or exclude specific apps from the client. Make sure you understand whether the mode proxies only selected apps or bypasses them: the same list can produce the opposite result depending on the mode. For advanced transport or security settings, check that the bundled Xray core supports them. A successful subscription import does not guarantee that every field is active.
v2flyNG: An Android Alternative for Existing V2Fly Configurations
The main reason to choose v2flyNG is its core, not assumptions that an alternative is lighter or uses less battery. If your existing configuration, documentation, or server setup specifically relies on V2Fly capabilities, the matching client can avoid translating fields between cores. You'll still need to import subscriptions, grant Android VPN permission, and configure background activity; the client cannot bypass Android's traffic-handling limits.
V2Fly and Xray are both part of the Project V ecosystem, but their capabilities have evolved differently. Sharing basic protocol names does not mean that every transport parameter, security option, or configuration format is interchangeable. In particular, do not expect Xray-specific features such as REALITY to work directly with the V2Fly core. Choose a client and core that match the configuration rather than just changing its displayed name.
If your current v2flyNG configuration works reliably and you don't need new capabilities, there's no need to migrate just to standardize app names. If your subscriptions mainly use Xray-specific features, v2rayNG remains the better Android choice. Subscriptions, routes, and app lists are stored separately by each client; installing another one will not automatically transfer all your settings.
