Jensen transformers - overrated?

I'm looking at passive DI boxes, and a particular one that makes a big
deal about having a Jensen transformer.

Does Jensen stuff live up to the hype or are they overrated? Most guys
I talk to in the audio field are quite positive about them but a few
have been a bit dismissive and I'm inclined to think they're just
trying to be "controversial" by bashing a popular product with a
(seemingly) credible reputation, especially as they can't quantify
their reasons.
