Do most clients do a constant throughput or do they do bursts? Because speed does matter a lot if it's burst (send 100MB to fill a buffer, then wait). The faster you fill whatever buffer, the faster you can let another client use the connection.

Correlated, but obviously bad code can really fuck with neighbors. And each client has an incentive to be greedy so users of that client get a better experience. So you fall back again to QOS for what you care about..

There are a lot of people who are the only ones using their Wi-Fi, so they probably don't care about the performance for anyone else

But this is the point. What your neighbour's are doing greatly affects the performance of your network.

If you have a good connection and are successfully able to transmit packets to your AP at 600Mbps, and your neighbour has a poor connection and is transmitting at 6Mbps to his AP at that moment, you literally have to wait ~100 times as long for a free medium before you can attempt to transmit. And that's for every single frame. Then you have to hope his client is well-behaved enough not to transmit while you are transmitting. Otherwise you end up having to wait again and retransmit anyway.

You might not notice this with only 2 clients. It might be the difference between a 80MBps and a 50MBps download for example. But it decays exponentially with the number of clients.
