This is one of those aspects of content development that people tend to pay way more attention than they really need to. It has been proven that the best kind of titles are the titles that hook potential traffic or tempt readers to click, since it captures a larger percentage of your traffic to your site. As long as your title is not obscenely long, it is pretty irrelevant. One thing you should keep in mind is to make sure your title is not longer than the search engines project, because at some point a part of your title will be cut off in the results. In this case, you want to get your point across as early into the title as possible.
The shorter you make your title, though, the better. It uses a similar logic as to why people prefer shorter domain names. Most people will skim through the results and not thoroughly read your titles, so you want to make it as easy for a potential viewer to read and plug in as much information as you can in the least amount of words possible to suit the time frame of their skimming.
