Would prefer triple-quotes, if only because they're familiar from Python. Backticks are less intuitive because of their historical usage in certain shell scripting languages.

Expanding my tweet-reply to @dherman: I use both Python (tripple-quotes) and Go (backticks) and I like backticks more: they are much more lightweight.

Also, you may find this email by Guido (he's against backticks) interesting: http://mail.python.org/pipermail/python-ideas/2007-January/000054.html
