# Best choice between using \\ or leaving space after each paragraph to end the paragraph

Here is the thing, I have always used a blank space between paragraphs in order to tell latex that there is a new paragraph. But there is someone I work with very often that keeps using \\ to break a line after a paragraph...

This is really annoying so I wanted to know if there is a real advantage of using \\ over just leaving a space.

Note that I am not referring to the paragraph environment, but to the simple term paragraph.

there is absolutely no advantage to using \\ to end a paragraph, and in fact, a big disadvantage -- it doesn't actually end the paragraph; it only goes to a new line, and probably triggers an underfull line report in the log.
there are only two ways to end a paragraph in "basic" text mode: a blank line, or \par. there are some (but few, and mostly obscure) situations in which \par shouldn't be used. but it definitely puts something "visible" in the file, and if you are sending a file using a mailer that swallows or "disappears" blank lines, then \par is safer.
never try to end a paragraph with \\!
@barbara beeton @Frank Mittelbach I don't understand why using \\  is considered wrong. I normally type paragraphs like this: \noindent Text text text text text text text. \\  \noindent Text text text text text text text. \\  And so on. In terms of style, I prefer to never indent the first lines of paragraphs, rather I refer only to leave a blank line (as above) to separate paragraphs. Anyway, if the above method works then why change? And besides, underfull hbox errors don't actually stop compilation, so I can ignore them. Pardon for my ignorance on this issue. –  User 17670 Aug 31 '12 at 22:18
