Fastest and smoothest UI?

[Veriac]

So, recently I have been interested in the smoothest custom UI that is available. No, I am not talking about ROMs or anything to do with rooting. I am speaking of TouchWiz, Optimus UI, Color OS, ect. Which one do you think is the fastest, most responsive, and smoothest out of all of them? I can certainly say, from watching videos and from my own personal experience that the Optimus UI is NOT the best. I've heard many bad things about Samsung's custom UI as well, but what do you think? I own a Nexus 7 and it somewhat isn't so responsive, but it is a year old.

I've heard many bad things about Samsung's UI, but personally I've never had trouble with it. My only caveat is lack of certain customization features and spacing for looks, but doesn't do bad in terms of responsiveness or smoothness. However, obviously the lighter UI is faster and incrementally smoother, so I'd say it's probably Sony and Moto at the top, being the least customized of all, barring Nexus devices.

My nexus 4 and 5 are the smoothest, and lag free phones I've ever owned. Next phone's gonna be a nexus 6.

Yes, people tend to complain about it but it actually seems more responsive than LG's. Thank you! I've never owned a Sony device but I would love to check them out now.

Sony's UI is not too intrusive, at least on my wife's Xperia U. I prefer vanilla Android which is one reason why I have a Nexus 7 and Moto G. my 'work' phone is an HTC Wildfire S running CM11 KitKat 4.4.4 and with an O/C to 806MHz not as laggy as you might think.

My G3 is the smoothest and zippiest phone to date. I even compared the battery life through a 12 hour shift to the iPhone 5S work phone I keep. The iPhone battery sucks compared to the one in my G3 doing the same exact thing. In 12 hours it is about half charged. The LG remains well into 70-80 percent.
