As much as I love the Nexus 6, the Note 4 is a better phablet for most users. It gets better battery life, slightly better performance under most metrics, and TouchWiz comes with enough extra features to not make it an overbearing UI skin. However, you'll prefer the Nexus 6 if you value stock Android and the ability to choose your carrier at will (due to the device being factory unlocked, even purchased from a wireless carrier). If the Nexus 6 had featured some of Motorola's own Moto UI features, then it would have probably been a closer matchup with the Note 4.
Then again, it wouldn't have been a Nexus device at that point - it would have been a Motorola Moto XL!
I want to suggest you to Samsung Galaxy Note 4.It offers High quality display and Robust configuration.It comes with 5.7 inches (Large) display,16 MP Primary camera and 3220 mAh, Li-ion battery.I have shopped this device from 91mobilescom, for me, its the best phone I have ever had
