Quickest, smoothest launcher suggestions?

Alright, all you Android "launcher" experts out there. I am looking for the most lightweight, smoothest, and quickest launcher out there that is close to stock Android 4.2. I will be putting it on my SGS3. I keep hearing it my be Holo Launcher HD, but also possibly Apex. I've tried Apex and really like it, but am I missing a quicker and smoother one?
