'Sin' -> '\text' for the sine-function and square brackets for function-calls when typesetting maths in Latex? Ah, good, it has a 'Copy as Latex', nice. The notation is just ugly, fine, that is personal, but 'Sin' as 'sin()'. This is akin to working with images in MS Word. The notebook interface does not have the 'auto-complete brackets' (maybe v11 does), so you add your first, all the text in the Cell gets reformatted and you have to find the fucking place you wanted end the bracket. The number of square brackets in your expression makes it necessary hard to read when it is big enough. '[' are used for function calls and for part-specification. Write a long line that starts wrapping, it gives it a little indentation to signify this, an your next line that you have indented is slightly more indented, but it is really hard to see, so you have no idea of where your line-breaks are.
You may go 'oh, neat' the first few times you try it then, at least I, get more and more frustrated on all the idiotic issues
The Mathematica notebook interface is horrible.
Personally I do not pay from Mathematica usage, so why do I like Jupyter more? The tie-breaker is social, not technical.
