The GE and PW philosophy was to cram as much as possible around the hot core section which means you need a pump to open the C Ducts/ Thrust Reverser halves. More time consuming and in my opinion more difficult access.
The GE CF6 is a brilliant bit of kit though. Incredibly reliable.
I agree, and would like to add another view:
Although being rather a desk driver and havn´t touched hardware for a long (too long?) time, I always found the wiring on the T700 (and other RR engines) superior to CF6 / PW for my part of the job - proper routings, markings, colour codes. It always seemed to me as if in GE/PW, the wiring guy came last in the design phase and had to find his ways along all the obstacles along his routes. And I somehow got along with the RR manuals much better.
