Note 2 is damn good (it was from Samsung's glory days, before it started releasing shit like grand, core etc but do check the condition thoroughly. I find it somewhat phishy that he is asking just 14K.
Ascend P1 :
pros : great screen, great camera, good enough processor for daily driver ( not for high end gaming) and quite a few ROMs already available on xda.
cons : average battery life and also battery non-user replacable.
Lenovo Phones run on mediatek platform. The lastest version on any mediatek device is 4.2.2. But if you ask me I would rather choose the Lenovo at 18K than increasing my budget by 3k and getting a nexus 4(horrible battery life and same on nexus 5).
E3. I dont see any cons except the battery backup. plus E3 has more custom roms than D1 ( seems Gionee completely forgot D1 exists).
Or If you can increase your budget, get Lenovo P780. its amazing.
