If it works, don't replace unless you go to a new crank with external bearings.
No offense, but it sounds like you have an opinion already and want us to confirm what you already want to do and then get mad when our opinions differ. In a forum, or in the real world, when you ask a question you will get a variety of reasonable opinions. Ultimately you have to weigh the responses and make a decision.
You have our permission to replace it. You also have our permission to keep it. Either option is not a big deal with huge pros or cons.
