Given how many people are comparing Scarfolk favourably to Look Around You, I think this image highlights why I feel like it falls well short of that comparison.

Looking at the dates on the blog posts, this is more "(then) current year politics in the style of 1970s British local authority PSAs" than anything that actually feels rooted in the time period of the style it's using. There's ones about COVID in 2020, ones about the election in 2019, ones about Brexit in 2017 and so on.

It's not bad, but I could almost look through the posters to see the author's Twitter feed at points.

To each their own. They have similar-ish (i.e. retro) styles, but their aims are not identical. Certainly, the intent of Scarfolk is to be eerie, whereas Look Around You is not intended to be creepy, merely absurdist, which is another area of contrast. I don't think either is better than the other.
