Neither, especially with Pocket. There’s something about an add-on integrated into a browser that makes me worry about privacy. I hate how pocket is bundled in Firefox and take great pleasure in disabling it in the browser’s config file. If it was something that could be downloaded on your own I might have had a different opinion about it. I just make a bookmark folder for articles I want to read later. It takes a few extra seconds to store and access but I think it’s worth it.
