They're pretty different actually. Medium posts feel like posting on Medium, Svtble feels like my blog and my voice. You can't design or monetize it, but that's not my goal when writing - it's about my words. Svtble is all about my words, Medium is all about Medium.

I always write on Svtble (because it's better and it's mine) and sometimes post on it later as a Medium post so I can submit to collections. But they are NOT one in the same, not at all.
