Fair enough, if you want to stick with the convenience of a phone that's perfectly fine. Yes, the V20 is miles ahead of the Pixel XL, the overall package it offers is much better. The biggest draw with the Pixel is the so called amazing camera. But guess what? The V20 camera is actually better, (16MP f/1.8 + 8MP f/2.4 rear with OIS, laser & PDAF 5MP f/1.9 front) >> (12.3MP f/2.0 rear 8MP front). Some other features that come on the V20 that you won't find on the Pixel phones ( microSD slots, a quad DAC that can only be rivaled by a DAP, a bigger screen, a second screen display for notiications, wide angle lens, dedicated mics for HD recording with isolation, a removable battery, MIL-STD-810G certified)...should I keep on going?......Also keep in mind the resale value for the Pixel is going to be horrid especially once those exclusive software ehancements with Google Assistant & etc wear off.
I agree with many of your bullet points, but the only one of them that's a priority to me is that Quad DAC. I don't believe at all that the V20 camera is better until that's proven.
Did the V20 switch to AMOLED? If not that's a second priority that they'd miss on.
Third priority, from a design standpoint, removable battery and microSD are both mistakes IMO and so on that front, the Pixel XL is doing better with more internal storage and a larger sealed battery.
Fourth priority, software, software updates, assistant, etc, etc. Don't think anyone will claim that LG's software is beating out Google's, but we can try.
Fifth, and above all, security. Google wins here hands down. The LG V20 is the one phone that comes closest to matching Google here, but the monthly updates will lag behind and it doesn't sound like the V20 has seamless updates, which makes it somewhat likely to EOL on Nougat.
So, LG V20 wins on Audio, Pixel XL wins on Screen, Storage, SoC, Software, Security, Battery Size, probably battery life (smaller screen, amoled, better software) and camera is unknown, but the only data we have is that the Pixel XL just rocked the camera standings and the V20 hasn't been reported on.
