Kryonet/Kryonet alternatives

Kryonet seems perfect for my first online project. But i’ve done alot of reading on TCP vs. UDP and UDP really sounds like a better option.

“KryoNet does not currently implement any extra features for UDP” - Kryonet’s github

Is there a library like Kryonet that is UDP based? Or am I being silly and TCP is perfectly acceptable?
