I've seen anecdotal reports on HN, but is there anything more substantive about how they do in relation to other carriers?

They get breaches far more often than other carriers. The black market price of a SIM swap on TMobile is reputed to be significantly less than ATT or Verizon (see relevant Darknet Diaries episodes.)
