I don't own one but I can tell you I've never even considered an LG until the G6
I had an iphone for 5 yrs then switched to Samsung 5 yrs ago. Nothings perfect but I've
always preferred the Samy displays since moving to Android. I tried an S7e for 20 days on Tmo and hated it, so back to my Note 4 I went.
I love the G6 in silver, (much better than the S7e mirror) I think it's one of the best looking phones on the market. I also prefer a flat screen with a small bezel any day over the edge displays. It feels great in the hand and has a solid feel, fit and finish is exceptional. I also prefer the 18:9 ratio over the 18:6 ratio of the S8.
I was concerned with the somewhat dim display on the G6 compared to my Note 4 but the S8s I've played with also have a much dimmer display. I've read numerous complaints about BT issues too, and while I love the wide angle camera I really wish it had an image stabilizer. The pics just don't seem as crisp as my N4. Guess that all leads back to my previous comment, nothings perfect.
Bottom line, well done LG!
