facebook is better to me.

both of them ...

I agree that you should use both. Some people like one over the other. I happen to prefer facebook but many people are all about tweeting.

Facebook has lots of options to do than twitter so i prefer facebook, but i use both in my campaign.

88% persons are aware of Facebook on the other hand 87 % persons are aware of Twitter.
Males make up 46% of Facebook users, on the other hand 48% of Twitter.
30% access Facebook via mobile and 37 % for Twitter.
You have to use both, then you can make a decision, which is your selection. Some people like one over the other.

facebook will give u the best and reliable traffic than twitter.

In reality, neither will do any good if you don't have any influence on them. The very first aim should be - to create a loyal audience and I don't mean just go on adding random people to grow your list, but people who are genuinely intereted in what you have to say. If you can do that, then facebook, twitter or any social network you name it - you'll be pulling traffic. End of...

Both are good on their places.

i recommend use both.. because these two sites have different social network tools.
