it's very good because it's simple and hasn't changed in over 10 years. you know it won't change, and it's the best $6.28 I've ever invested (but of course, I wouldn't pay for it every year; I would find another solution).
I'm glad people are mentioning Wallabag. It's open source and self-hostable, so it's not as likely to disappear on you. If you don't want to bother with self-hosting, there are some hosted options available: https://github.com/wallabag/wallabag/wiki/wallabag-ecosystem...
I've run Wallabag before but stopped around the time my son was born so I'd have more time to take care of him. And... I switched to Pocket. Oh well! I guess I'll switch back now, probably for good.
