Cytomel,
Keep in mind that you did not have to lift the bar as far sumo as with conventional. Hence, the weight at the top of the lifts were different because you were using bands. The farther they are stretched, the more force they exert.
So to really tell if one way is better for you, you will need to deadlift without the bands. You probably know this but I wanted to make sure you were mixing apples with apples so to speak.
