[One (M8) General] high_voltage:
I had desire hd - a great, great phone for it's time and defo in the top level. Custom kernel and ran on me @ 1.45GHz daily driver, no overheating, better GPU performance.

I had one X - a really great phone in any way, rooting/custom kernels tamed the hot tegra 3 and make it a joy to use: heavy uv on all SOC levels not only CPU(uv on system, uv on gpu, leading to massive drop in working temperatures like never seen), OC, Gpu @ 520MHz a lot lower temps and I had easily 4:30 hours SOT + whole day heavy use.

I have now M8 - when it came out it was one of the best devices for sure in every way... samsung was on galaxy s4, lg on g3 etc.

Now all changed. While htc 10 is a good phone, it's overpriced for me and by much. It shine only with headphones audio, but that gets it only that far. Screen is nothing that special, camera got it's problems, htc started to streamline too much the sense(dropping the good apps like galery, most likely due to cheaper approach to use the google ones), overheating that comes in 4-5 mins gaming, heating under light use, QA problems, speaker sound is so low that it negate the quality, slow games loading times, etc, etc - nothing to shine. Overall good device as reviews says, but nothing special while the price here is the same as S7 edge that comes with a lot more - water resistance, wifi charging, super amoled, bigger screen, dust protection, a great camera, good headphones sound too, cold in hands in light use and heating only around 35 degrees in heavy games while performance is great, games load fast as f, no throttling, great battery life! One of our members can play real racing 3 for 7 hours till battery drops dead while on the htc 10 he got only around 4 and worse performance. Etc, etc, I read/watch/checked enough to know that the s7e is the better phone and the price of the htc 10 is just insane for what it is. How can you expect to make it out of trouble financial situation if you release overall good, but not that great phone with QA problems to the price of s7e that is not only advertised tons, but a great device? Dunno, but for me right now s7e is just the best android phone you can get. Oneplus 3 comes for me @ the same price that rule it out. Axon 7... I want software updates and development after all, so no. Nexus? Can't wait for the next and for me s7e is better than 6p and yes... here 6p is the same price also. So, yeah... looks like soon I will have silver s7e. I don't look only on one manufacturer and be a brainless fanboy. I had 3 htc phones, because they where great, in the top tear and even for me above(I put every single one of them higher vs samsung/lg etc in their given time) and ofc I like sense a lot. Yeah, but things changed and htc didn't adapt itself - price like the top tier phones, but nothing shining above them. Good headphone audio can't make it that far, especially as s7e have dedicated good DAC also... not that far behind on headphones. :)

TBH from what I saw of htc 10 - it's not that much better than the state my M8 is right now to justify the 600$ price I would get it:

Performance: Real world performance of 10 is slower than my M8 right now. Apps load slower, overheating drops the performance of 10 while M8 stays strong + smoother scrolling/UX.

CPU: 801 is a great SOC and proves it again and again. It doesn't heat that much and keeps the performance high even when warm, while 820 starts to throttle hard and heats even faster.

GPU: 530 is great, but the a lot higher resolution and the overheating are both dropping it's performance to just a tad above 330. Nothing to brag about - needed for the QHD resolution.

Camera: M8 camera is totally not that bad if you know what you are doing with it.

Speaker sound: M8 had two speakers towards you - more balanced and true stereo sound in landscape, louder too.

Software: running A9 sense7_g right now and that's great. Have the option for partial or full sense8 port...

Screen: fullhd on 5 inch good screen and qhd on 5.2 inch good screen. Similar.

Battery life: I can easily get 7 SOT and full day of heavy use. Nothing more to say... maybe I will have a little more on the 10, but nothing worth the move and defo 7h SOT is enough. With a lot of gaming and youtube I still get to over 5H SOT and whole day.

Htc 10 get so many positive reviews as it's compared to M9 flop of a phone that even on custom ROMS/kernels is still overheating bad camera mediocre phone worse than M8. Compared to two years model of them it's not that great at all. Better for sure, but not by much for two years of advancements.

Yeah, I dislike TW too, but not that much as before. Samsung are moving in the right direction and now tw is a lot better(shaping to be even better in the android N).
