This is one of the best phone in 8k with snapdragon 615 chipset. Yes there was heating issues before. But after the official update from yu to cyanogen 12.1 it is buttery smooth. No lags, no heating issues etc .
And cyanogen 13 is also expected in near future
Camera quality is excelent. As it has sony lens used for rear camera with 13 mp. Front camera of 5mp is quite good for taking selfies. U can go for it if your price range is around 8k this is a good choice
