I didn’t say that you should start an FCP Vs. Avid thread. The problems you’re having are not normal, and you are doing yourself a disservice by not asking about your issues in the FCP forum.
If your FCP system is in such a condition now that makes it unusable, I would imagine that your Avid system would eventually fall into the same state of disrepair. They are both based on computers and both need preventive maintenance.
Even when I have been forced to rely on editing systems that I’ve not been keen on, I have always gone out of my way to make sure they perform as best they can.
I have used both FCP and Avid. They are both good editing systems. I have even been a champion of Avid where I work.
