The V40, like the V35 and G7+ before them, are quite serviceable. LG really did some nice work from an engineering lens in 2018.
The weight is nicely balanced, the screen is still sharp and the notch doesn't both me one bit. The extra screen real estate is fine, especially since I use a slim case that doesn't add much bulk. Everything else is typical LG.
What annoys the hell out of me is how slow switching between the lenses have gotten. I can bounce between the four focal points on the Mate very quickly.
If I were to pick, I would have gotten a V50 with the bigger battery or the G8 with the triple camera over the 2018 lineup. Now, Huawei has a better overall setup for stills on the Mate 20 Pro. Their telephoto is more versatile, and with better photos. I actually like using their telephoto lens, as the regulars here have seen. I'd still trust the LG manual mode for stills and video over Huawei out of preference right now. But that may change as I learn the Mate 20's camera.
I still prefer the G8 footprint. I actually liked the G8, but at the prices I had seen, and coming off the V35 experience, I didn't want to pay the $100 extra for another AT&T variant.
