Battery
If you love the flexibility of swapping in a new battery when the current one runs out, neither of these curvy smartphones are likely to make you smile.
It's too early to know what the battery life will be like on the Samsung Galaxy S6 Edge, but the 2600mAh power pack doesn't offer a whole lot of encouragement on this front.
By comparison, the G Flex 2 packs a 3000mAh battery (reduced from 3500mAh in the previous model), but before LG can boast about having more power, there's the matter of that larger 5.5-inch display to consider.
Thankfully, the fast charging capabilities of both models should have you back in action quickly – our own review of the LG G Flex 2 topped up from a complete discharge in just over an hour and a half.
Cameras
Samsung hasn't held back when it comes to the Galaxy S6 Edge camera: Rocking a 16MP, f1.9 aperture sensor with dual LED flash and optical image stabilization capable of shooting 4K video up to 3840 x 2160, the rear camera is no slouch.
By comparison, the LG G Flex 2 borrows liberally from the LG G3 to provide a 13MP sensor that otherwise checks off the same feature list above on the Galaxy S6 Edge, although the laser auto focus is one noteworthy addition.
Neither model breaks much new ground with the front camera, however: Samsung touts a "best-in-class" 5MP sensor with 120º wide angle lens, while LG's tops out a 2.1MP, which the manufacturer claims is enough to use it as a "full HD camcorder."
Features
The remaining feature checklist is relatively the same for both handsets: Each ships with Android 5.0 Lollipop out of the gate, with the usual Bluetooth 4.1, NFC and 802.11 a/b/g/n/ac wireless on board.
Aside from curved edges, the Samsung Galaxy S6 Edge also offers built-in Qi and Powermat-compatible wireless charging.
LG instead opted to include a selfie-friendly "Gesture Shot" mode on the G Flex 2, which provides a three-second timer on the front-facing camera that can be activated with a gesture; tilting the camera down allows the user to review images instead.
Like the original G Flex, the sequel also features that bizarre self-healing back, which didn't do all that much to impress in our own review of the G Flex 2. More impressive is the Glance view, which offers a peek at what's happening without the need to actually turn on the device.
Galaxy Edge 6 vs G Flex 2 Verdict
This two-horse race ultimately comes down to just how curvy you want: Along the edges of the handset with the Samsung Galaxy S6 Edge, or on the entire smartphone with the LG G Flex 2.
LG has a slight advantage since the handset is already available from two carriers for early adopters to take home, but to be honest, the whole concept of curved displays on a smartphone still causes us to scratch our collective heads more than be impressed.
Samsung isn't likely to woo many potential Galaxy S6 buyers away from the flagship device in favor of the Galaxy S6 Edge either, but those in search of a more premium edition worthy of making friends envious will want to wait it out a bit longer – assuming you can afford it, that is.
