The mechanical connection, I'll give you. If you don't intended on disconnecting the feed line more than a handful of times a year, if that, then TNC is a more secure connection.
Again, for the purposes of monitoring with a consumer scanner, the BNC is more
than capable. Changing it out for a TNC is, frankly, overkill.
