From the benchmark perspective, no it's not. Dual A9's usually equal to quad A7's in CPU power, while SGX544MP1 is obviously superior to SGX540. However, the bloatware those small manufacturers tend to put in those MTK devices will obviously slow the phone down. Words around the internet also say that although MT6589 is a quad A7 CPU, only 2 cores are used per normal task.
I suppose you're gonna buy a device - don't buy MTKs, there's usually no development for them, they may never get future Android upgrades even via flashing (because there's no custom ROM at all), meaning that your phone could be dead on arrival. Personal opinion so feel free to oppose.
