I personally don't have the patience to read a book with just braille on a braille display. I am way quicker on actual braille paper, and have less of a problem with that, but obviously braille books are bulky and impractical for most situations :)

Until there's a good multiline braille display, I use braille mainly for looking at things in detail, when I'm coding, spell checking or working with foreign languages for example.

For me, it depends. If I just read a news article, I don’t mind using a screen reader. If I, however, read an actual book, especially, when it comes to a fictional book, I prefer reading it on my display. When I read a book, the characters in it always have different voices in my head. Including the narrator. That just wouldn’t work with a TTS voice. Plus, a TTS voice will never hit the right tone for a certain part in a book. Action scenes, sad scenes, funny scenes, it will always read it in the same tone. I don’t think, I could ever concentrate on that for a longer time.
I also think, reading an actual book, will improve your spelling, as well as your grammar. A lot of my friends are completely blind. And with most of them, you just know, that they only use screen readers. Their spelling is just terrible. And they never use punctuation. That is some thing, I noticed with a lot of blind people. Head over to the audio games forum, and you will know what I mean. You can always tell, who uses a display, and who only uses a screen reader.

Not really, I prefer Braille, I comprehend things better when I physically read.

I'm about 4× conventional audiobook speed with my screen reader' although as I've aged I find it easier to fall asleep and lack concentration. Still if I haven't got my gsplay or am doing something with my hands (gardening, washing-up, etc) tts all the way.

I do. Reading with a braille display is too slow and I sometimes forget what the paragraph was about when I reach the end of it. Beside, I'm a non-native English speaker and because I've been using JAWS for years I have the best comprehension when Eloquence reads the book for me. I read using this TTS on Windows and on Android, using an app called @Voice Aloud Reader. It's kind of like an old friend reading the book for me.

I do, simply because when I'm reading braille, I turn the page and forget what I just read. This was a huge problem in school.

I have a braille display connected to my computer and use it in conjunction with my screen reader. Most of the time, listening to the speech is more efficient, but I like having access to the braille for proofreading and things like that.

I personally prefer a screenreader to braille. Be careful, I think it has its uses, such as when coding for example, but for things like reading a book, social networks, etc ... I prefer the screenreader.

Well you know it is a whole, complicated thing, with me! I am eternally grateful that I was educated juuuust before laptops and iPads etc were integrated into the mainstream classroom, forced by circumstance to learn Braille as a child. But it's true that after secondary school I kind of left it behind in favour of screenreaders and digital files (except for mathematical subjects, which were impossible for me without paper and Braille), for much the same reasons as you (a limited, conservative selection of titles, too bulky, too slow to produce.) Still, Braille literacy is a valuable asset, rare as it may be these days, and it is crucial for congenitally blind children (the reasons for that could fill a dissertation), even if the delivery system changes. (Braille itself must never die, but the form of it, the enormous embossed books chosen for us by printing houses and charities, that stuff could be on its way out in certain countries, now that we have refreshable displays and can read regular old ebooks and digital Braille files downloaded off the Internet.) If there was a multi-line display that could be afforded by ordinary humans without having to rely on pity cash from the government, I feel like I'd be using it almost as much as a screenreader. There is something about the slowness and intimate physicality of reading Braille that makes every word stick in your mind, in a way that simply doesn't happen when using TTS, for me. During my studies I would always use Braille if the option was available, because I took it as a given that all would be forgotten by exam time if I read the textbooks audibly. The problem is that the tiny one-line displays we have now aren't exactly ideal: you either have to press a button every 5-10 words to move to the next line, or tell it to automatically refresh after a set period, so that you can never establish your own reading rhythm because you're always either waiting half a second for the line to refresh, or reading faster than you're comfortable with to get to the end of the line before it refreshes, which, as you say, is all a big distraction when you'd rather sit down and just…fucking…read. Maybe I'm using it wrong?

Tl;dr: yes, I do all my casual reading with TTS and it works great, but sometimes, I wish there were better options when I require the immersion of Braille.

I’m pretty slow and I feel like Braille takes a lot of energy out of me. I only know Grade 1 but will be learning Grade 2 very soon. So yeah, screen reader is fine for reading but an absolute pain for editing, which is why I’m getting a Braille display.

I've not read braille for literally anything in 18 years. Screen readers all the way

I prefer tts.
