Several similar errors across several addons (AutoCategory, Inventory Insight, etc.)

LibDebugLogger seems to have become the gold standard for error reporting to devs. BugCatcher is convenient too, simply because it prevents error message boxes from appearing center screen while to are in mid-battle or in a trial or something and you die. It does have the "bug bag" on-screen to let you know that you've encountered an error so you can go look at it - after the battle.

I still like BugCatcher to avoid center screen message boxes, and because the font is bigger.
