Bristol will give higher offers to students with deferred entry, as they don't want to disadvantage students who will apply in the next cycle. Other places treat deferred and current applications equally, and some places favour deferred places in order for you to get relevant work experience.
Really, I wouldn't worry. If you don't get your dream uni this year, you're always able to re-apply in the next cycle! (this is most of why I'm not panicking about my application too much)
