The HTC U11 is the larger phone. It's about 3-percent taller and 5-percent wider.
Unsurprisingly, the U11 is also about 4-percent heavier.
Both makers opt into the glass-on-glass trend that's spreading to premium smartphones. They both have glass backs and aluminum frames; the frame is less prominent on the G6.
The HTC U11 has more color options, but availability depends on region. Here, the asterisked variants are not available in the US.
The LG G6 has a slightly higher water resistance rating, but either one should withstand a quick splash or dip.
One of the U11's headlining features is its pressure-sensitive sides. Depending on the app, giving the phone a squeeze launches actions like snapping a photo and launching voice-to-text.
It's a novel way of increasing touch interactivity, but the value of this hardware feature will depend on how well software developers put it to use.
Like the Samsung Galaxy S8 and S8+, the LG G6 opts for a large display that's relatively tall and narrow. The G6 squeezes in a touch more overall display area than the larger U11.
Both phones have QHD displays that pack in the pixels.
Both makers go for IPS display technology over AMOLED.
The LG G6 supports HDR 10 and Dolby Vision HDR, so it can support HDR content from Netflix and other services (when available).
The HTC U11 hangs onto the physical home button below the display. The G6 has an onscreen home button.
The fingerprint sensor on the U11 is embedded in the home button. On the G6, it's on the back.
The HTC U11 contains the latest Snapdragon 835 processor, which clocks in ever-so-slightly higher than last year's still-capable Snapdragon 821.
This pair has a matching 4 GB amount of memory.
The U11 offers twice the amount of built-in storage. Both phones are available in only one size.
But if storage is a concern, you're covered either way. Both phones have microSD slots for expandable storage up to 2 TB.
The HTC U11 supports Hi-Fi audio. In the US, the LG G6 does not, though this feature is available in some international markets.
Despite catering to audiophiles, the HTC U11 took a cue from the iPhone 7 and axed the traditional headphone jack. An adapter is included in the box, but otherwise you'll need to use either USB-C or Bluetooth headphones.
HTC has also included a pair of wired USB-C U Sonic headphones, which offer some degree of active noise cancellation.
The LG G6 has a slightly higher battery capacity, though of course many factors beyond size go into overall battery life.
Both phones support Quick Charge 3.0 fast charging.
The LG G6 supports wireless charging with a charging pad (sold separately), but only in the US version.
The HTC U11 actually has higher resolution in the front camera than in the rear. It should take much sharper selfies than the LG G6.
Camera aperture (rear)
The U11 also has a slightly larger camera aperture, which could mean an incremental improvement in depth of field effects and low light shooting.
Dual lens camera
The LG G6 has a dual lens rear camera that combines a standard and wide-angle lens. When shooting, you can toggle back and forth between the two to fit more or less into the frame.
Optical image stabilization (OIS)
Both cameras use OIS to combat hand shake and blurry captures.
Since both are NFC-equipped, you can either one to use Android Pay at participating retailers.
Tech companies are getting increasingly competitive with their AI-driven voice assistants. Like all new Androids, both of these have Google Assistant, but the U11 also comes with Amazon Alexa and HTC's own Sense Companion.
Both run Android Nougat skinned with a manufacturer UI.
The HTC U11 is available for pre-order now and starts shipping in a few weeks. The LG G6 hit shelves earlier this year.
Starting price (full retail)
These two phones have different approaches to premium, but they're at the same price point. The HTC U11 is available unlocked for US$649, while you can expect LG G6 prices to fluctuate a little more depending on payment plan and carrier.
