I have an LG V10 on T-Mobile. I got my Google Pixel (not XL) last week and so far I love it. Haven't used the V10 since. Like you I was going back and forth between the Pixel and V20. I haven't looked at the V10 yet.
I'm not a heavy app user. I have Facebook, a couple games and a few other apps. Pics, sure. With kids and dogs I take a lot. But it's nice that it's saves them.
Love Google Assistant. It's very nice. I'm using also an LG Platinum Bluetooth headset and I absolutely love how they all work seamlessly.
No bloatware since I got it from Google Store. I like the app tray. The fingerprint sensor works flawlessly.
So far, only complaint is battery life. I love the USB type C and it does charge quickly. My battery life complaint is similar to most other phones though. I haven't seen or found one smart phone that lasts all day with even moderate use. My LG V10 I had a Zerolemon extended battery. Made my phone a brick but it did last.
Also if you get the Google Pixel or any new phone with USB type C and have the old USB micro chargers I would certainly get some adapters. I got some from Amazon pretty cheap. A 2 pack and I also got a car charger.
I don't see needing more than 32 GB unless you have tons of large and heavy use apps.
Looking forward to Googles VR but looks like it will be at least a month or so. That kind of drinks.
I have a rubber case I got from Amazon and screen protectors. Screen protector needs some work. It's okay but slight gap around edges but it covers workable screen.
I am going to post this in the LG V20 forum as well but I want view points from BOTH sides. I know there will be some bias which is why I will do that.
I am returning my iPhone 7 Plus tomorrow and moving to Android full time. The 128 GB Pixel XL is back ordered until December. The 32 GB Pixel XL is shipping November 2nd but with twins on the way I need something with more storage. I will be taking a lot of pictures, videos, and I like to have movies on my phone. I do not feel 32 GB would suffice.
The LG V20 is in stock locally and reviews have been great. I like the 5.7" screen and I also like the 2nd screen on it.
I have never had a Google or LG phone so I am looking for advice. Thanks!
