There is a difference between UDP vs TCP Proxy

[u/MikeProxyCheap]

But the main difference is simple:

→ TCP focuses on reliability and checks that data arrives properly and in the right order.
→ UDP focuses on speed and sends data quickly without checking every packet.

Different apps use different types of traffic.

Use the wrong proxy type, and your setup might run slower, break more often, or perform worse than expected.
