If you ask to me, backticks should always be used. But there are some reasons why a team may prefer not to use them.

Advantages:

• Using them, there are no reserved words or forbidden chars.
• In some cases, you get more descriptive error messages.
• If you avoid bad practices you don't care, but... in real word, sometimes they are a decent way to avoid SQL injections.

Disadvantages:

• They are not standard and usually not portable. However, as long as you don't use a backtick as part of an identifier (which is the worst practice I am able to imagine), you can port your query by automatically removing backticks.
• If some of your query come from Access, they may quote table names with " (and maybe you can't remove all the " blindly). However, mixtures of backticks and double quotes are allowed.
• Some stupid software or function filters your queries, and has problems with backticks. However, they are part of ASCII so this means that your software/function is very bad.
