Default [Q] What's the smoothest 4.3 TouchWiz ROM?

I've been running 4.4.x ROMs for a few months now, but am getting tired of the two issues that seem to be consistent across all of them (at least for me). 1) GPS frequently drops. 2) My Gmail won't load embedded images.

So, I'm thinking about going back to a TouchWiz ROM. It looks like nothing much has changed in the past few months.

Can somebody suggest which is the smoothest TouchWiz ROM available right now? Or TW ROM setup (ROM + kernel + mods/tweaks).
