For my 2 cents worth. My opinion is, all of the various Yuzu strains and yuzu hybrids are simply not worth investing ones time and money in growing them, and most especially if your intent is to eat any of them.
I have a different opinion from you. I can understand why some people would say that. Yuzu is not really a "high quality" fruit, compared to any normal lemon. But it has no bad off flavors, is definitely possible to eat, and is pretty hardy and cold tolerant for a lemon. That combination of hardiness with edibility could be a good starting point, in my opinion. It may not be an excellent fruit, and it does not have the level of cold tolerance of poncirus hybrids, but can you find any other citrus that is as cold tolerant as Yuzu which tastes as good, or is as edible as Yuzu but is more cold tolerant? I don't think you will.
Yuzu is great to add flavor to other things, and especially the peel is tender, not too bitter, and has lots of flavor. Something else to keep in mind is that harvest time does matter.
Those who say Yuzu is terrible, I have to imagine that those people live in a zone 9 or 10 climate where they can grow better tasting citrus varieties. Once you get into zone 8, your options become more limited, and then Yuzu might be something you might want to consider, if you want to be able to grow anything outside.
Unless you value Yuzu for the peel and understand how the peel can be used, I can see how some people might not understand how Yuzu is worthwhile to grow. But the inside is edible. Although it can be a little watery and bland, the inside flesh is a bit dry, does not have much juice, and of course the inside is packed full of a large number of large-sized seeds that take up a large volume of space. I get a lemon, sour orange, mandarin orange, and a little bit of almost grapefruit flavor from the inside segments.
When I say the inside is edible, perhaps I mean something that a child would snack on and forage for in the wild, or that you could eat in a survival situation.
Yuzu has a very fragrant and unique smell, that to some people compensates for its low quality fruit. The important thing is that the fruits do not have bitterness, like some other fragrant orange citrus fruits.
