Curl gets another point for having better SNI support, as wget versions until relatively recently didn't support it.
This means you can't securely download content using relatively recent (but not the newest) versions of wget (such as any in the Ubuntu 12.04 repos) from a server which uses SNI, unless the domain you're requesting happens to be the default for the server.

As an example, I found the file https://redbot.org/static/style.css only accessible with SNI. Try `wget https://redbot.org/static/style.css` vs. `curl -O https://redbot.org/static/style.css` on Ubuntu 12.04. Domain names which point to S3 buckets (and likely other CDNs) will have similar issues.
