What is your opinion?
1. The secret of 'unlimited' is actually buried in the Terms of Service by the host. Do not be surprised to find that unlimited only equals 900mb or so.
2. The host may restrict the sort of files that you can host on their server. Generally, image galleries and audio/video files attract a lot more downloads thereby resulting in higher bandwidth consumption. So if there are no files of this type, your site won't really require a lot of bandwidth.
