No lagging , IR blaster works fine . Soc is good camera is average, no3.5mm jack type c , storage is only 32 gb . or have a look at Lenovo zuk z1, redmi note 3 , moto g4 plus hope that helps
But lenovo zu1 has no ir blaster
Moto g4 has heating issue
Redmi 3 has not good camera
Overall displya of leeco 2 is best out of this
