RetroBat might be a bit more popular than Skraper. We know about 2 links to it since March 2021 and only 2 links to Skraper. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
Edit: A third way, if I recall correctly, is to use the Skraper app from skraper.net. It uses a GUI to let you scrape metadata and assets from screenscraper.fr (and, hopefully, maybe import some of your own art and assets?) and I believe it also builds a gamelist.xml for you. I think I used this method the first time I set up an RG351M on 351ELEC, and the metadata format used there applies to many of the games... Source: 10 months ago
You can give Skraper a look at skraper.net. You'll need a free screenscraper.fr account, and there are daily limits to how much you can scrape without waiting or paying them a bit, but you should be able to poke around and see what's there. Source: 12 months ago

If you're familiar with batocera stick with it. If you're more comfortable in windows use the windows unofficial batocera (that the real batocera team tweets support for). It's called retrobat. Find it here: http://retrobat.ovh/. Source: about 3 years ago
