Hey everyone, looking at current network development trends, both TCP and QUIC are gaining traction. If you had to pick the best underlying protocol for large-scale future applications, which one would you lean towards? Share your reasons, and feel free to roast me.

Personally, I'd still lean toward TCP for now, especially since QUIC (while promising) is still relatively new and lacks widespread server-side support outside Google/Cloudflare stacks. But for high-latency mobile apps where connection drops matter, QUIC’s built-in multiplexing + 0-RTT recovery feels like the future—we’re testing it on our internal API and so far it cuts wait times by ~30%.
