I've been blocking JS for the last 6 months or so and I've found it to be a greatly improved experience overall. I can enable at the click of a button JS for a website that fails to load properly but the majority of sites I view are fine without this. It was refreshing to learn that not as many websites as I suspected are JS abominations!
My experience exactly. Everyone said "don't do it, most sites need js!" but it isn't true. SPAs are certainly out there, but not nearly as common as you'd think (I most thank SEO for that since only recently would Google crawl a client-side rendered page). Will it be a seamless experience? No, definitely not, but I agree, overall it's an improvement.
I do have Firefox set to noscript. When things don't display, I copy the URL to Chrome where I don't have it so locked down. But I've been dismayed to see over the last year that a lot of sites that used to be usable no longer are.
