I use them both and niether is better really. They are close to the same specs, the mrc has slightly better specs and power, but maybe a few less features. It also comes with a nice power supply , and if you want to use on AC POWER THen that's worth something.

I think the linit for T-2 is 5S and the 989 is 8S for lipos and the current limit yopu posted is correct. 7 amps, and 10 amps.
