Best phone ever. I owned it through mi store 20 days ago. awesome Android experience. I strongly recommend you to buy this phone if your budget is 7k. It's a all rounder phone with awesome battery life and nice camera.There is very little difference between note 3 and 3. But yes note 3 is better than redmi 3, better gpu and better processor. Keeping that in mind I would say the performance will be better on note 3. I have been using note 3 for about a yr. And I am happy with it. Though while using u wont notice that much diff, But on a technical aspect there will be a nano sec or a few nano sec difference. When we talk about processor speed, core usage and data handling capability of a processor. Since these are metal body phones there may be a lil heating ( dont worry wont cause burns or bruises) , which is normal. Overall rating a good phone in this price range.
