SocketAsyncEventArgs vs TcpListener / TcpClient

Consider an example scenario:

Client 1. One information as a message 2. Send the same data message 10,000 times to the server 3. Connect to only one server at a time

Server 1. receive a message from 1000 clients simultaneously (if possible, if not, as far as possible) 2. Cancel the received message in memory (no need to write to a file)

This scenario is easily implemented using TcpListener / TcpClient. However, I need to emphasize the machines.

Which one should I use; SocketAsyncEventArgs or TcpListener / TcpClient? What for? Can this script use reusable SocketAsyncEventArgs?
