Which is better a blog or a website?

That depends on what you want to do with it. Websites are far more customizable, but also take more work to manage.

the best thing is having a website because blog just share information but website can share anything like downloads and more

of course website is more better, you can control it in full. I think you have to clearly statement. blogs is for your personal activity and website for commercial activity.

It depends. A website has more scope for laying it out exactly as you want. A blog is more limited. I use free blogs for making money and they work for me and are easy to use. Mike. http://mikesmoneymakingmission.blogspot.com

Why not have both? If you are using blogger, it's a bit limited, but if you have wordpres there are options to create static pages. You could also create a website with a "blog" on it (have a look at http://www.rhyswynne.co.uk for an example of it), also you could have a blog, with website built around it (have a look at http://www.gospelrhys.co.uk/blog.html for an example) It's entirely upto you. If you want say a fairly static pages (such as general information that wont change, or a list of software), a website is the best. However, if you want to be constantly updating and fluid, a blog is the best way forward.
