My 02 sensors came out really easy. I can't understand why some are difficult to remove. I used an old craftsman 7/8 open ended wrench and gave it a few gentle taps with a hammer and they came loose easily. The 02 socket sometimes will bind and get caught up around the wires. Those sockets flex because of the open side and sometimes don't work well. The new 02 sensors come with anti-seize already applied so I assume that the factory ones would have that on them as well.
