domain suggestion

I want to buy new domaindomain.Now what is the difference between .Com and .info domain ?
Is there any performance difference between them ?
If i buy .info , will it cause me any trouble ?

Now days, a good .com domain is very hard to get. Yes! .com is better than .info .
You can find that there is big difference in reputation of both extensions. However, there is no difference in technical performance like DNS still you can get extra benefits from .com.
Sometimes .info considered as a spam by search engines without any sound reason but it is not in case of .com
.com has better search engine visibility.
