I use Raindrop[0] for all bookmarks and have flirted with Omnivore and Wallabag over the years. But I always come back to just using Raindrop and "Unsorted" for my read-it-laters. I've got a feed into Reeder from here which works well too. At the end of the day a likely next step after reading something is to want to bookmark it so this workflow works well for me.
