Moto G turbo is the best phone under 15k. Moto G trubo edition is same as the Moto G3 the only difference between them is processer and also the charger. Moto G3 doesnt have tubro( fast) charger. While the other specs of the phone is same.
While talking about the design Moto G turbo is little bit of thin than the Moto G3 and also the back panel of the Moto G turbo is better than G3 panel. The Moto G turbo is light weight.
As I see the only main difference of the G turbo and G3 is processor, G3 comes with snapdragon 415 while G turbo comes with 615 processor which is way better than G3 thats the only reason G turbo is 2k costly then G3.
The camera quality of the phone is same both comes with 13MP primary camera and 5MP secondary. Both have 5inch dispaly even the design and the material used in both phone is same. The ram of the phone is also same both comes with 2gb ram and 16gb internal and expandable memory upto 32gb. Both have dual sim platform. For me if processor is does matter for you in mobile phone than you have to consider this phone first.
