The Nexus 6 is one of the biggest phones you can buy today, but both handsets give you good screen size to phone size ratios (in other words, there isn't a lot of bezel surrounding their screens).
Specifically, the Nexus 6 is 7 percent taller, 9 percent wider and 3 percent thicker than the LG G4.
The LG G4 is also 16 percent lighter than the Nexus 6.
For the G4, LG is giving you a choice between a leather back or a plastic one. The Nexus 6 has a plastic back, but aluminum edges, which (since your fingers tend to notice the sides first) gives it a more premium feel than you might expect.
The leather and plastic versions of the G4 each give you two color options to choose from.
The G4 gives you 85 percent as much screen real estate as the Nexus 6. If you want a big screen, but aren't quite ready to go whale-hunting, then the G4 could hit a nice balance point.
Both phones have ultra-sharp Quad HD displays, but the G4's smaller screen gives it a 9 percent higher pixel density.
The G4 uses an IPS panel (which LG describes as "Quantum IPS," with supposedly higher-than-usual contrast), while the Nexus 6 has an AMOLED one.
Camera megapixels (rear)
The G4's rear camera has higher resolution, but that doesn't always mean much when it comes to camera quality. Stay tuned. The Nexus 6's camera is good, but in a phone full of impressive features, not necessarily one of its highlights.
Camera megapixels (front)
The G4 continues a recent trend we've seen of flagship phones with front-facing cameras that could have been rear cameras a couple years ago. Apparently selfies have grown that popular.
The G4's rear camera has a slightly wider aperture.
One of our favorite G3 camera features returns in the G4, as it fires a laser that will (quickly and automatically) measure the distance between sensor and subject.
The Nexus 6 has a higher-capacity battery, and it tested well in our battery benchmark. We'll have more on the G4's battery life when we review it.
The Nexus 6 supports Qualcomm's Quick Charge 2.0 tech, which can take it from an almost-dead battery to about 50 percent battery life in around 40 minutes.
Only two internal storage options for the Nexus, and one for the G4.
The G4 does, however, have a microSD slot to complement that internal storage.
Both handsets have a healthy 3 GB of RAM.
The G4 has a slightly newer processor, though it's hard to complain about the Nexus' performance, as it zips through stock Android about as quickly as you could ask for.
Both phones run Android Lollipop, but the Nexus 6 runs the "pure" version, with no manufacturer customizations like the G4 has.
The Nexus 6 launched last November, while the G4 still doesn't have a firm US release date (it's already available in LG's home of South Korea).
Starting price (full retail)
US Carriers still haven't announced pricing for the G4. The Nexus 6 gives you solid bang for your buck, at US$650 off-contract (large phablets with high-end specs usually cost $100 more than this).
Starting price (on-contract)
The same thing goes for the G4's on-contract pricing (for what it's worth, the G3 launched at $200 on-contract).View gallery - 22 images
