I agree that it is security by obscurity but when I ran SSH on port 22
it was syslogging at least several hundred login attempts every day,
currently I run it on port 422 and it's never had one single login
attempt that wasn't myself. Obviously you have to make sure it's also
secure regardless which I do by requiring that the login is either with
a key, or if with a password it also requires a one-time-password 6
digit code read from an app on my phone.
So if all the login attempts bother you, moving the port certainly
works. Just make sure you also keep it secure in other ways.
