I view all such claims of great edibility suspect.
Dunstan and Morton both have comments about how you can avoid segment walls...I think it's just mostly about fruit being bigger and juicier and not necessarily better.
Again, we really have a problem with people talking about how inedible or edible these things are. Citrange/Citrumelos/Citrangequats/Citrandarin etc, are all quite edible, for the most part, and they are better than many marginal fruits. So people hype these up. However, real citruses (kumquats sort of excluded) are far more edible than anything with poncirus in it, so plenty of people disdain trifoliate hybrids unnecessarily. We keep bouncing between these extremes, and should stop doing that.
I mean, my own tree, when fully ripe in December, has no off taste at all, and the rind is exactly like an orange and is even a bit sweet. There's no skunk taste in an otherwise orange-lemon taste, and only perhaps a little terpentine taste that diminishes as it goes from mature (tastes more like Ugli fruit) in Nov to ripe. The only real barrier to enjoyment is the strong caustic aftertaste and plentiful seeds. Were there citranges like this a hundred years before they were created, they'd almost certainly have become part of rural cuisines. There's no reason to get excited about my tree, but it's not chopped liver, either.
