Meizu m2 note is an excellent device altogether, the camera, the smooth functioning, the build quality all are top notch in this price point. Definitely coolpad note 3 has a larger ram and a fingerprint scanner, but if you dont want that and you are willing to settle for a lesser ram but similar gaming, better camera and better battery then you can definitely go for it.
Build gives a look like the I phone but the functions are obviously the Meizu ui.
The battery will last easily a day and a half on moderate usage and dont forget it has the fast charging ability as well so you get a good lasting battery combined with the fast charging or else batteries dont last and u just keep on fast charging them which then serves no purpose whatsoever.
Camera is snappy fast clicking but not only does it click and capture pics fast but at the same time it does take good quality pictures and with proper precision, the front camera is also of a top notch quality and does take a good amount of selfie in this price range or rather I would even say it exceeds in camera more than other devices which are there upto the range of 20k.
Im not posting anything much in details because I own a coolpad note 3 and Im pretty happy with it it costs me a little less but still I needed a power bank just in case which you would not need if you are planning for a Meizu m2 note. Choose wisely both r d best but it depends what are you willing to go for is it the extra ram or is it the extra battery and power charger or the power bank with an extra 1gb of ram which I own.
Hope this helps
