Direct splice versus cabinets and patch panels: Direct splice is less expensive, reduces vulnerability to vehicle/plow damage, easy to test the drop cable, and only a single location needs to be visited to turn up a customer.
Cons are increased difficulty in troubleshooting and potentially reflection from unterminated cable (though I have not seen issues and several other have reported no issues).
