Best OEM in 2017

As we all know, there are alot of OEMs which we use in our smartphones. It is basically a custom ui which is provided by the companies in their smartphones.
There are many custom UIs available such as MIUI, ZenUI, Touchwiz, EMUI.

We may be well aware of MIUI, it comes pre-installed in xiaomi devices. It provides great customisation options. Almost more than all of the above mentioned names.
MIUI is a chinese UI just like Honor's EMUI and Asus's ZenUI.
Some days earlier, MIUI 9 was launched with great new features like split screen, home screen assistant, new themes and many optimizations were done under the hood to improve the speed of device.

Now, let's talk about EMUI and ZenUI.. both are chinese OEM's UIs.
EMUI is kinda having more features than ZenUI.
But it has less features than MIUi.
We can say that MIUI>EMUI>ZENUI.
Zenui mainly focus on camera optimizations and less on features and customisations.
It is somewhat like stock/pure Android ui.
Although it's not exactly same. But it reflects stock ui.
Anyways, last one is Touchwiz..it is the ui which is provided by Samsung in their devices.

There was a time, touch wiz was very slow..it lags in devices because of it's heaviness.
But now, Samsung has improved a lot.
Now it runs smoothly... Samsung added alot of new features too.

But still if your need is features/customisations.. you should opt MIUi
And if camera is important then Zenui,

You should opt for samsung if you have more budget.. like go for s7,s8. Then it's good. It's budget phones aren't good.

Honor is good for it's ui. It's smooth. But with little less customisation options..

So choose wisely.. and decide which oem ui is good for you!
