The important thing is not where but how. What matters is a platform that doesn't get in your way. You need something that helps you focus on writing while keeping useless distractions (such as colors, formatting or html) away. Medium is good for that and so is the distraction free mode of WordPress. You can always write on Word and copy and paste the text later too. You can even use notepad or wordpad. I generally use metapad for this. In my personal case I find markdown very useful when I absolutely need some formatting but don't want to waste time with HTML, toolbar buttons or having to remember keyboard shortcuts. The great thing about it is that it doesn't break the flow, I can just keep writing. For publishing (which I do rarely as I mostly write just for my own amusement) I use Neocities because it's just old school HTML and doesn't get in my way, GitHub pages work for that too. The good thing about those two is that backups are basically hassle free, you always have a local and a remote copy and don't have to worry about having to backup a database or export a blog (as is the case for Medium or WordPress). Since you asked for cons too: static site generators and GitHub commands not only are something else you have to install, learn and keep up-to-date, they also break the flow so only use them once you've finished writing. So here's my summary: choose whatever platform you feel that doesn't get in the way of your writing.
