I've pretty much tried all of them @tobixen and keep coming back to Steemit.com. I like the simplicity of it.
Like you, I couldn't get on with esteem app on my phone and didn't like the web version much better.
Steempeak I don't like because of the way things look in the feed. I prefer the list like Steemit produces but they've said there isn't enough interest in it for them to make it a priority.
I use busy.org to store draft posts at times and publish through there as well but I don't find it easy to move around for replies etc.
It Steemit had a draft saving feature I'd be happy! 😊
Ulog I just don't get the point of at all and have struggled to understand all the posts that have come out about it.
