Websites Host .net

I know about free webs and like google sites, but are these just as good as sites you have to pay for?

like if i make a site for free what are the disadvantages from that rather than paying for my own domain name and host and whatever. Do both get placed in search engines equally? Is one favored? etc.

Search engines do not care how much you spend, free hosts with a proper domain name will do as well as paid ones.
