they could just be relying on as_path+bgp bestpath
but yeah, i personally prefer a model of
localprefs in this order (highest first obviously)
customer
peer
upstream
this puts traffic across links that you get paid for,
you get for (free?) a lower cost than upstream/transit then
the most expensive link.
