Oubadah:TeaLeaf: I think you can do better for the money if you are willing to go chinese. The Redmi note 3 is far superior and even the meizu note 2 should perform better.
What's the software situation like on those phones? The SU6 is comfortably close to stock android. Do they even have the google play store?
I think it depends on the version one buys; a newly released phone appears to sometimes only come with a Chinese-specific ROM, so no Google Play, but international ROMs for phones like the Xiomis are easily available (if not not so easy to install!). The Redmi Note 2 I got my wife came with an international ROM which has Google Play as well as many other Google apps; apart from seeing some occasional Chinese script in the settings (and problems with updates), there's little that gives the phone away as a cheap Chinese device.
(Personally, I'd have bought the Smart Ultra if it had supported Spark frequencies - but it wasn't shifting networks just for the phone...)
