I think this is a bit unfair. If you have worked in an LFS or elsewhere you will see that many of these tangs die far more rapidly than due to water quality or other issues. They don't ship particularly well.
While there are exceptions to every rule, IME and listening to other people on this board, I wouldn't call a PBT a "hardy" tang. Now maybe yours is, and that is great and worth noting that they can do very well. It is actually a compliment that you have kept a good specimen in good health.
But overall I think people need to consider the experience of a number of hobbyists which is why these boards are great. Yours has done well, but that doesn't mean as a whole the group of fish should be considered hardy. This is true of many, many fish and other animals in this hobby. Some people can keep flowerpot corals no problem - but for most they die. Some people can keep Linckia stars without problem - even in smaller tanks - but most will die. Some people can easily keep moorish idols, but most will die. So its great that you have had no issues with your PBT, but I think it is always wise to be cautious in describing such fish. It can go with some more aggressive fish if it is well established and healthy...but many will have significant issues and that is worth being very wary of. I would feel much more comfortable recommending a naso, vlamingi, yellow, sailfin or purple to a large aggressive tank, over a PBT (blue or brown). JMO tho.
