If you're only doing ethernet, the 7600 makes a great platform and can
do almost anything a 12000 can - but being essentially an ethernet
switch as soon as you start adding non-ethernet interfaces into the
mix it can get expensive, as you need the intelligence to
encapsulate/decapsulate the packets appropriately in the line card.

The most annoying thing about the 7600 is the lack of MAC address
counters, which unless you're using individual VLANs/private
interconnects for every peering session makes peering decisions rather
tricky at times.
