We use 2014 T6 over 7075 because 7075 is such a "hard" aluminum that if it will go, it tends to snap instead of bend (6061 T6 will also bend before it snaps). In the end, 2014 T6 is superior in every possible way to 6061 T6 with the exception of raw material costs as 6061 T6 is substantially cheaper.
