I think many brewers use agar now which comes from seaweed or something. Prices in homebrew shops seem similar to isinglass. I’d guess the agar price in bulk may be more stable with less dependency on fish stocks.
I don’t notice any difference in taste. The isinglass/agar is just for clarifying, it’s not in the final product in more than trace amounts. But any type of clarifying can change taste based on what and how much flavour it removes.
I never noticed the difference personally. guiness has never been a very flavorful stout anyway though, it’s more about the creaminess and that its available when there’s nothing other than lager.
Lots of trendy modern ales go ‘unfined’ (cloudy) to preserve all flavours.
