Currently running Pie Controls and GMD Gesture Control to assist in application switching and other quick shortcuts. Not sure if I'll keep both I'm relying on Pie Controls more.
With Titanium Backup I've frozen a bunch of applications including Allshare, ANT applications (3 of them), samsung's backup app, Blurb Checkout, Business Week, Cisco Webex, E-Meeting, ELM Agent, Facebook (I use the web page), FWUpgrade, Gallery (I use Gallery KK), Play Newstand, KLMS Agent, Magazine Widget, Music (I use Google Play Music), My Magazine (I use Nova Launcher, the stock launcher sucks), Netflix, NY Times, Pagebuddy Service, Remote Controls and Remote PC app, Samsung Push Service, Scrapbook (no intention of using it), SideSync (dont have other samsung phones), Software Update, Weather and Briefing.
Freezing those applications keeps them from loading even as cached apps freeing up space in RAM to cache other apps that i frequently use.
In addition I uninstalled all Knox related apps.
For other mods I'm using Xposed Installer to do things like per application DPI settings to render things in smaller fonts, block ads, disable nag screens (location consent, modify share menus, modify complete action windows etc.), control what starts at boot (boot manager) as well as a few other tweaks.
