I used to use GoLaucher for a long time then I realized that every update just got more laggy. I've tried a few others, but looking for something that doesn't use too much memory. My most recent test was Turbo Launcher, which used 45MB of RAM. Default seems to be the fastest, but has limited options. Just stick with original?
I use Apex. I just like the way it looks. I've never considered how much memory it uses. Nova works fine too, I just like Apex more. I'm not even sure why. What device are you using? Is that your N7?
I use Nova Launcher on my N4 and the default launcher on my N5. My wife uses Nemus launcher on her S3... I prefer the MI Launcher, but last time I tried it there were some issues with English language. Smart Launcher is pretty nice and quite fluid....also quite basic. i tried "Everything.Me" launcher when it was in beta but it was never even remotely stable.
using ZooperWidget Pro here.. not really a launcher, but i use it that way.. https://play.google.com/store/apps/details?id=org.zooper.zwpro
Apex on my Nexus 7, but stick with Sense on my HTC One X. Not really a fan of stock Android visually.
Trebuchet because it has Internal wallpaper rendering and the ASUS Transformer is too old to support all the new Phablet UI layers that KitKat has, so the dev added an option to disable System wallpaper rendering and let the launcher do it instead, which returned the silky smooth experience that the old Tablet UI had On ROMs that still have Tablet UI mode, Apex or Nova - I think Apex was my favourite
I'm flitting between Nova Launcher and GEL(Google Experience Launcher) Nova is just the best IMHO but having Google always listening is so handy it is fast...... Daily is Nova though
Using Nova on both my Nexus 5 and Nexus 7. No issues as of yet and its a much better launcher than the default one.
I always used Nova on my other phones! But since ive got Nexus 5, ive been using default Google Now one. Love the option where you swipe to the right and get all your google cards!
Nova here, love the smoothness and customisation options and the backups for app folders and home screen layout is a nice time saver when i try a new ROM.
My Daily is now GEL with the addition of Xposed GEL settings, i can have it just as customizable as Nova, but with all of the google features...
Using Apex launcher here. Smooth as butter. Tried Nova launcher but it doesn't run as smooth as Apex launcher on my low end Mediatek (MT6572) Chipset phone.
