Yes it’s among the weird super sweet ones, all of them seems to be not okay for my SO and I. They are just not nearly as sweet for us as they should be. Like, stevia mixed with xylitol or erythritol (it’s a big thing here), they are mixed in a ratio that they are supposed to be 4 times as sweet as sugar. And we don’t feel it so much sweetener but it’s not normal. We don’t perceive the weird, unnaturally strong sweetness as sweetness, more like some awful taste. Something is there but it’s masked by a very bad taste.
Monk’s fruit was one of the worst things I ever tasted, stevia is a bit better and tricky as it was always awful when I bought it (the leaves are already like that) but I ate chocolate sweetened with stevia and it wasn’t so bad, they can do something well that I can’t just mixing stevia into things. Even if my sweetener mix has 1% stevia and I use a little in a food, I can’t handle it, it’s extremely bad tasting. But I have my own sweeteners so all is well
My fav is lactose as it’s even carnivore and usually comes with some very tasty, fatty thing 
I don’t know what they are but as I wrote, food industry apparently can do something about it indeed…
I don’t even know sugar prices at this point but I don’t care if my sweetener is 10 times more expensive. Especially now that I almost never consume any. But allulose is crazy expensive. I rather buy some deer with that money… Sweetener isn’t food, isn’t necessary, isn’t even very important most of the time. The caramellization effect is neat though… But my sweeteners make my cookies a lovely color too, it’s enough for me 
(And I can handle even honey here and there so if I want some more expensive - but nothing crazy - sweetener - in a wide sense so something that sweeten things so all sugars are included -, I can buy that. No sweetener is tastier than good honey though I quite like coconut sugar too with its caramel flavor. I don’t have it since years but I have nice memories.)
The sweetness is quite individual. Erythritol is allegedly 70% as sweet as sugar or xylitol but I feel it way sweeter than my SO. I figured it out when I tried to make cake with erythritol instead of xylitol and he complained about the lowered sweetness while it was okay to me. Our sweetness perception was the same back then.
If I could buy a tiny allulose, I would try it out of curiosity…
That has no chance in this household since almost 1.5 decades
I usually used a quarter of the sweetener amount for the first time. A few months without added sugar and we already felt sweet things WAY sweeter, no matter how much natural sugar we ate, it’s interesting.
But I usually make my own recipes even if I use one as a base. I have my own preferences. If something uses too much sugar or replacement, it’s tough as it is probably needed for the texture but I only know one not really sweet sweetener, maltitol and I won’t use that. Meringue never can be my thing, oh well. Ice cream is doable, too bad I never want it. I still eat it sometimes, it’s useful to use up leftover yolks and cream.
