WiFi repeater: to distribute to a neighbor or not?

Question

Computer networks

Hello,
I rent an apartment in a private house. My neighbor and I have equally average-bad signal to the host's WiFi hotspot. I installed a repeater with a good antenna.
Question. What is more profitable: change the network name (+password) and use it yourself (WiFi devices, LAN on PC), and let the neighbor continue to be content with a low signal; or - leave the same network ID and password and "allow" the neighbor to use the repeater?

I understand that with a worse signal, the neighbor will "influence" all network devices (and mine too). And in this case, it may be more profitable to connect it to my repeater. Right?

Thank you.

If you are not concerned about security (as if a neighbor connected to you via cable directly) and users have modern devices (WiFi works on the worst standard for backward compatibility), then it is better for everyone within a radius of 100 meters to use one seamless network.
