California has been the best. Hawaii was pretty good but mostly because they were so chill and nice. Los Angeles was the most strict but most engaging in conversation. They picked apart my lockpicking set, then let me in after making sure there wasn't a knife tucked in there, talking about the hobby the whole time.
Pretty sure the worst TSA award goes to MCO though. I dread flying through there, even with pre.
Even within the same airport it seems to differ. I flew international out of JFK for the first time in a decade a few weeks ago and had been hearing horror stories of what to expect. Yet when I got there I spent less than 15 minutes in line for security, spent less then 60 seconds going through the actual security scan (metal detector, not x ray scanner) and was treated perfectly fine.
