Already bought the Moto Z from Expansys (through Lelong) for RM 2,350.

Coming from HTC 10, here's my unbiased comparison of the 2 devices:

Both HTC 10 and Moto Z have great build quality but the back aluminum of the Z can easily get scratched (just an assumption since I got the unit with a small hairline scratch already)

In-hand feel:
HTC 10 is definitely more comfortable and natural in the hand. Moto Z is way too thin and I resorted to using the included Moto Style Shell and bumper to add thickness and hence, a bit more comfy.

Software UI:
I'm good with either HTC Sense or Motorola's vanilla UI. But I'd give a point to HTC since the UI adds more personalization to your phone.

Hardware/Software add-ons:
Definitely a big win for Motorola. If you have used any recent Moto phones, you know how useful moto display, moto actions, moto voice are. This is one of the main reasons why I switched back to moto and the reason why Samsung and iPhone imitated the moto display feature (but moto display is still miles better)

Touchscreen responsiveness:
I am a bit disappointed with the Moto Z as it is not as responsive as the HTC 10 (although reviews tell us that HTC 10 is touted to have the best touchscreen latency of all smartphones)

Fingerprint:
Both have their pros and cons. Both are capacitive to the touch but I find the Moto more accurate in reading my fingerprints. Never had I experienced any misprint BUT I know for a fact that HTC 10 has one of the best fingerprint scanners in the market.

Sound quality:
Again both have their pros and cons.
HTC 10 has a "cinematic" sound whereas the Moto Z's single front-firing speaker sounds more solid to my ears (it has that "oomph" I'm looking for from HTC One M8)

When connected to earphones, both have very high volumes. HTC 10 is the benchmark  for its superb sound but Moto  is not too far behind. I'd say Moto Z has more bass (if you like it) but the HTC 10 has the perfect and evenly sound overall.

Front camera:
OIS is a great help to HTC 10's front camera, the quality is similar to Samsung's. I'm not a fan of the oil painting look of the HTC just to smoothen out your face.

Moto Z's front camera is realistic but a bit dimmer (HTC 10 f1.8 vs Moto Z f2.2). Both have 1.4 micron pixels so the lens is big. However, the front dual LED flash of the Moto Z really helps for indoor shots (and yes, the quality is good with warm color skin tones).

Back Camera:
HTC 10 wins. Hands down BUT it's not to say Moto Z is an awful shooter. It also has OIS, f1.8 and laser auto focus. It's just that HTC 10 is a more reliable shooter. Ultra fast auto focus and capture unlike the Moto Z which I feel you need to have steadier hands in order to shoot great photos.

Sorry for the very long post. I'm in the mood to type and provide my unbiased views :')
