[LG V20 Questions & Answers] Nitemare3219:
V20 is pretty smooth. Not always quite as smooth as the Pixel XL is, but very, very close. I've only been using the V20 for 24 hours, and I miss the Pixel XL in some ways, and not in others.

-The V20 definitely is the more capable phone. Tons of features. The Pixels are just plain boring - they work great, but lack anything special.

-I miss the AMOLED screen, but love having a 5.7" screen again on the V20 (coming from Note7 and 6P) - it's a dramatic difference, exacerbated by the additional top ticker display. If you love, love punchy color that is nowhere near accurate/realistic, the V20 display will disappoint you if you've used AMOLED before. But I actually use my Pixel XL in sRGB mode. The V20 is slightly, slightly more saturated, but extremely cold with its whites. I have to use the night-time comfort view set to medium 24/7 to get anywhere near an accurate, warm white. Personal taste here. Qualcomm is supposed to have some TruPallate thing built in that changes saturation/color temp based on your environment - I've yet to see anything from this.

-Camera comparison is a bit of a wash. The Pixels have much better dynamic range, and better selfie detail, but the V20 typically has more detail overall (due to being 16MP - not always the case though!) The V20 also has the best camera app and manual control, bar none, if you're into that. And it has an always-ready wide angle camera, which few, few people will ever have access to.

-Great sound quality in terms of output and recording. The Pixels are meh. I have audible noise with my $1,000 IEMs on the Pixel XL. The V20 is crystal clear.

-Not much to comment on in terms of battery life. I don't expect much from the V20 with its smaller cell and larger display, but I had bugs on the Pixel causing CPU times to be insane giving me garbage battery life.

-Power button/fingerprint scanner on the V20 is kind of ****, at least how it feels. Without a case, it's hard to find. The button feels cheap when you press it, as do the volume keys. But my Pixel's power button has QC issues too - it sticks, badly. The V20's scanner is mostly just as fast though, which is great. Sometimes it misses or reacts a little slower to the way I land my finger on it, possibly because it's a smaller sensor than the Pixel (and I'm not using a case on the V20 yet which makes it harder to find), but it's probably the best FP scanner I've used other than the Pixel's.

-Haven't really tested sunlight legibility yet, but the V20 will get brighter than the Pixel XL out of the box. If you root and use a kernel to activate the Pixel's HBM, it is brighter than the V20. I imagine the Pixel XL is fairly better in sunlight due to this, and its less reflective display.

-Pixel XL seems to have a better speaker.

-V20 has a much brighter camera flash for pictures, but slightly dimmer flashlight (at least the built in one - could be modified probably with root). The Pixel XL's camera flash is much better for color reproduction and skin tones though.

I really can't decide between the 2 phones. If the Note7 were still around, and actually a good performer, it'd be in my hands still. The V20 would have been perfect to me if it had an AMOLED display. But don't be mistaken, it's a great phone and actually gives you some features for your money. The Pixels are like iPhones... they just work, really really well, and that's about it. And the days of that being a huge advantage are coming to an end with Android OEMs finally maturing with their software optimization.
