In your opinion, over the years which U.S. Mint has the most problems or reputation for produces the most error, variety or anomaly coins?

Philadelphia? Highest mintages by far, so presumably that results in the most errors, etc.
On a percentage basis the Dahlonega Mint in Georgia. They made many misteaks.
Produces the most, or the most that get out?
The mint doesn't make these 🙄
Yes, numbers alone and statistics would suggest that.

Maybe we're (I'm) getting too far down in the weeds.

I suspect that more recently, quality differences between the Denver and Philadelphia Mints may be, in part, related to different die crown heights and design heights.
2012: It is reported that:
"All coin designs are modeled and digitized or produced digitally. Master
dies are prepared on digitally controlled milling machines at the
Philadelphia facility. Master dies are distributed to the Denver facility,
which produces its own working hubs and dies. Despite using the same
masters, the crown heights of dies and design heights of relief produced
at the two facilities differ, which has a measurable effect on coin fill."

Excellent question. What if they all have the same error rate per million coins, but Mint "X' was better than Mint "Y" at catching them? I've seen pictures from back in the day of struck coins riding a conveyer belt past inspectors who were supposed to be hand picking out the errors. If I had been one of those inspectors very little would have gotten past me. However, I know people who would let a lot of stuff escape their attention.
I saw what you did there!
