For starter, lets begin with the spec. Assuming bigger, faster, thinner and lighter is better.
The Sony Xperia Z Ultra definitely had advantages in terms of spec compare with the Ninetology U9Z1. The Z Ultra had bigger screen, beautiful Triluminos display with full HD resolution though people tend to said the 1080p and 720p won't have much difference. Well maybe yes maybe no. Here sample photos of comparison in terms of screen.
Processor, RAM and ROM
The Z Ultra gain advantage by equipping fastest processor at the moment, the Qualcomm Snapdragon 800 which running on cortex-A15 while the Ninetology U9Z1 using Mediatek mt6589 that features cortex-A7. Both quad core but definitely in real life Z Ultra will perform much better when come to heavy application and gaming. Not to mention 2GB RAM onboard help multitask smooth sailing. Xperia Z Ultra also come with expendable microSD slot.
Physical Design & Built Quality
With omnibalance design, Sony Xperia Z Ultra is made with 2 glasses on front and back with aluminium frame on side. It is definitely feel solid on hand especially the weight is a bit heavier than Ninetology U9Z1. Not to mention it is one of the slimmest full HD display smartphone with 6.5mm thickness. Meanwhile, I said before that Ninetology U9Z1 easily been mistaken as Samsung phone from front while back resemble alot HTC Sensation XL. The Ninetology back casing was built with aluminium too. I won't deny that the U9Z1 feel solid on hand too. Realistically, it is more practical to have Ninetology U9Z1 due to size and able to hold it with one hand than the giant size Z Ultra. But who can resist the sexy beast? :P
This is the part where Sony really did poorly. Megapixels is not everything but what Sony always lack on their smartphone is the better image processing hardware. The details easily get smudge and not sharp. No doubt Ninetology U9Z1 image is sharper (too much sharpening! and look abit artificial) and look much better than the Z Ultra.

Well not until when come to indoor shooting where the U9Z1 white balance tend to screw up and show warm color. Sony still manage to retain the neutral white balance but not the best too. Ninetology U9Z1 had advantages too on 5MP front camera to compare with Sony Xperia Z Ultra 2MP only. Unfortunately the front lens is fixed focus in the U9Z1.

Video Playback and Speaker
Here I did a video for both phone. Personally, it is much better experience viewing on Sony Xperia Z Ultra due to the size and also Triluminos display.
The Sony Xperia Z Ultra is waterproof smartphone rated IP58. The Ninetology U9Z1 came with wireless charging features.
The Z Ultra has larger battery life than the U9Z1. However both has come to the point where it can easily achieve SOT around 5-6 hours. It is pretty impressive for both devices. However Sony Xperia Z Ultra came with remarkable Stamina Mode that extended the battery life during stand by.
User Interface (UI) and Android Version
Both run Android Jelly Bean 4.2. Sony Xperia Z Ultra skinned with their very own Timescape UI while the U9Z1 is running vanilla Android with minor customization. Naturally, Sony Xperia Z Ultra provided more software features such as Walkman, Play Station and more eye candy themes while vanilla Android is just plain. Nothing much to shout.
Not surprising, with impressive spec came with high price. Sony Xperia Z Ultra is one of the top notch smartphone when come to performance and the RRP fixed at RM 2,299. The U9Z1 is more on budget concious phone that come with high performance, if it is last year flagship that priced at RM 1,199. It is almost 50% cheaper than Sony Xperia Z Ultra.
Both are very capable phone for your daily usage. Of course, if performances is much more important to you, Sony Xperia Z Ultra will be better choices. If budget is one of the reason to constrain, I have no reason to say why not Ninetology U9Z1?
Ninetology U9Z1 will have direct competitor such as Google Nexus 4, Samsung Galaxy Mega 6.3, Samsung Galaxy S3, HTC Desire 600, Huawei Ascend P6, Huawei Ascend Mate, Alcatel One Touch Idol X and many mores. Sony Xperia Z Ultra will be facing current latest flagship such as Samsung Galaxy S4, Samsung Galaxy Note III, Sony Xperia Z1, HTC One and mores.
