I am subscribed to Medium although its hard for me to say if its worth it for you or not because my currency is extremely over valued. I def read a lot of articles on there but I don't know how many of them would count towards the 3 per month. (I thought this is actually 3 'premium' articles per month or some bullshit, I believe they could've changed their rules but I thought that not every article counts towards this limit only ones where the author tries to monetize on Medium exclusively.) Most articles I find worth reading are published somewhere else also tbh.
