296 is only really from slow modems. Even 576 is a bit low for a 56K
modem. It depends on what you use the connection for. A lower MTU gives
slightly better responsiveness for IRC, gaming etc. A higher value gives
slightly better throughput.

However, the question is often academic as some dialup servers, such as
Cisco, only work at 1500 so your TCP stack falls in line with what they
want.

As does Genesis. The setting is only a preference, the actual figure is
negotiated during connection.
