Problem with Robinson and such squash stuff is aside from the dubious nature of sweeteners, there’s not much fruit in it (didn’t used to be any, just flavourings, now about 10% if you’re lucky).
At least fruit juice is fruit juice. Okay that’s naturally high in sugar. Didn’t seem to matter in the past and we got a healthy portion of fruit, vit c etc, and I don’t recall anyone getting fat just on fruit juice. But sugar is bad now m’kay (purely because statistically fat bastards cram too much sugar, therefore war on sugar. Same as happened with salt).
I use 50% high juice to flavour my riding water (and add a pinch of salt). Still squash and some nasty bits in it probably and being from concentrate the fruit juice probably isn’t that beneficial, but it’s half fruit juice and not mostly flavouring, colours, etc. I’m in two minds whether the sugar free or added sugar is better. Basically need energy in there, but then was put off the sugar from a story about a runner (or may have been cyclist, or both) who was downing energy drinks and gels and claims to have gone diabetic as a result. Flavouring water in the office though, no added sugar stuff but it does come with that questionable sweetener stuff.
