My verdict: an absolute MUST-HAVE, free and magic when it works.
An absolute MUST-HAVE. It's free, you scrape in one click. It doesn't work everywhere (complex sites), but when it works, the simplicity is incredible.
It automatically detects tables and lists. For hassle-free occasional scraping, it's the extension to have installed.
What I like less: it doesn't work on complex sites (SPA, infinite scroll, anti-bot protection). And no automation possible.
My advice: install it now, it's free and takes 30 seconds. You'll use it more often than you think.
