By bigger site, I mean a site with more content on it.

By floating to the top, I don't mean that the algorithm picks the site with most content and puts it first, the second biggest second etc., but that a larger site helps getting to the top.

Why would it help?

• More content means more words, which means more keywords.
• More content means more pages, which means more internal anchors.

So, does anyone reckon that this is the case?

First thing you should understand is that search engines do NOT rank websites they rank webPAGES

Nope, dont believe that for a second.

Just because a site has more content, doesnt mean its better than any other.

This would be a silly metric to use and I highly doubt google even look at this.

Well if the new algo change by Google is any help to go by, bigger doesn't mean better. Read this.

And anyway, do a website for users, not bots. More than ever before, you'd rank better that way.
