I have, and own both 700's and 70's.
Have never had a 70 fail me hunting/shooting. Have had 700's break extractors and action lock up.
Got the extractor issue fixed, and the trigger/bolt lock up issue resolved with aftermarket trigger.
When I am on a more involved hunt, say Africa, AK, out of state or 7+day hunting camp. My Model 70 classics's get the nod.
Have everything I need, and do not see me ever purchasing another 700. But if a classic catches my eye, will never say never.
