Are Infinix phones any good?

tl;dr Are Infinix phones reliable?

I've been looking to upgrade my phone from the 2014 Moto G, and I was wondering if anyone has tried Infinix phones?
The have caught my attention considering their extremely low prices for relatively high specs (I'll list the specs below for those of you who haven't even heard of the brand). I am a bit reluctant towards buying a Chinese phone considering their reputation for being of low quality as well as the phone's small battery since MediaTek processors are power hungry.
Here are the specs of the Infinix Zero 3
