The fact is that there is no empirical data showing one type of ESC being more likely to fail or dangerous than any other. Everything is just anecdotal: "There's more pictures on the internet of this one melted down" or "Well 3 guys at my club had this brand of ESC smoke on them". Even failure rates reported by Castle or Tekin have many variables that are unaccounted for, so it's questionable to call that empirical data also, but it's the closest we'll get.
