Should obfs4 port be 443?

Hi - I’ve got a bridge configured with:

ServerTransportListenAddr obfs4

Metics show it’s working fine, with a connection rate of about 15-20 clients a day

I see that quite a few configs you see posted have obsf4 on port 443 or sometimes 80.

Is there some advantage to this? Does it mean connections to the bridge might be easier from restricted networks perhaps?
