While 'best' is a very qualitative adjective not suited to sites that attempt to provide factual information, there are a number of excellent sites that can provide free content for your Sims 3 game, not the least of which is EA's own site. Their are also sites like Mod the Sims, which is free, and thus, legal. Sites that ask for you to purchase their content, or to pay a subscription to access some or all of their content (or ask for mandatory 'donations') are in direct violation of EA's EULA for The Sims 3, which you can read here:

Special attention should be directed at Section 2, Subsection B, Paragraph 4.
Go to Sims3.com and go to the 'Exchange' tab of the website.
Well, one good website that I highly recomend is The Sims Resource. I always get my custom content from there and the quality is awesome. Also, you can go to Mod The Sims which is quite good.

and the sims 3 website.
You can find custom content on various third-party websites, or by downloading pre-made Sims with custom content from the Sims 3 Exchange.

If you're talking about custom content, there are many places you can go. The first place is the Exchange on the Sims 3 websites. Another popular website is modthesims.info, it has a lot of content free for download. A simple Google search will pull up other websites.
There are Sims 3 custom worlds, and you can find them on a variety of websites in the Internet.
most websites don't make you pay to download custom content. but there are a few sites that make you pay a "donation"
You may get custom content from the official Sims 3 Exchange. However, if you would like more variety of content, there are always third-party sites such as The Sims Resource and SimsVIP. You may find the links to these sites below.
