how are O2 sensors?

bank one sensor one has been replaced and the short term and long term are ok

update

i was monitoring post cat 02 sensors and bank one was running lean and compared to bank 2 was a big difference . the vehicle had a tune up done at another shop recently . the plugs for the 02 sensor are side by side and plugs are the same so i swapped the connectors and the post cat sensor started acting properly problem solved . thanks to everyone for all your help
