I was perfectly fine with my OnePlus , until my father took it from me for his Note 3 (He loved the OP). I did not like the Note 3 at all , and they were dropping in price Fast (and i mean Fast).
I have a very good friend in the market who was v interested in the Note 3 , since it was literally brand new. He took it for 42 ( which i think is a very good price). I wanted to hold on to something untill the Nexus 6 arrives and settles down in price. The S5 came in my range and they have a good resale as well. So opted for a brand new S5 (G900F LTE)
Still i would highly recommend OP over anything that is currently available in the market. Under 40k range that is.
