I have no problems recommending the Honor 8 in that trade. At this point, the GS6, albeit a good phone, is starting to show its age due to recent updates. Samsung devices do tend to show a bit of sluggishness over time too. As someone who has owned the Honor in the past, its really a slick little device. The biggest downgrade is really in the screen resolution as the Honor 8 panel is only 1080p. However, I think you'll notice a big bump in the battery department. Both phones posses fairly heavy skins on top of Android so I don't think you'll notice anything different there. EMUI (Huawei's Honor skin) does not have an app drawer (all your icons show on your home screen). However, this is easily fixed by installing a launcher if you choose. The fingerprint gestures on the Honor 8 scanner are also a very unique feature. I'm a big fan!
