So, been using both Steemit and Busy to try and see which one I liked better, and still undecided. I use steemit most of the time, also because I have the notion that most users use Steemit, and this i important when posting. I've seen that posting through busy ended in a URL that was less clean, and since then I've been posting through Steemit (DSound and DTube aside).
This post is the best and most up-to-date comparison I've found on this important subject, and it touches upon the most important thing (to most users I guess): UI/UX. The writer thinks overall Steemit is preferable, mostly due to performance speed, as he admits Busy looks better, has more functionality and a better post editor. For me, as a creative person who is less into text and more into multimedia, I also find Busy's embedding abilities attractive, as they are way better than Steemit.
As far as DTube goes, it is flowlessly interfaced into Busy, while on Steemit you only get the link. You can start playing a Dtube video from your feed without even entering the post. As for pictures and photos in the posts, in Busy you can click a picture/photo in a post and see its original size, while on Steemit you just have the static picture in the post, and if it is big in dimensions then it is just sized down to fit the post width and you lose most of the visual info.
So I don't know, I guess I wrote this in order to start a discussion and perhaps understand how people use both platforms to access posts on the Steem blockchain; So I would love to hear everbody's opinions and thoughts, please do let us know how and when you use either :)
