It is harder to pull Touch/Go then DeadStop for me - for some it is not the case. I don't think it matters at all (I know it doesn't and it I use it as a litmus test) because if you pull 800 for 10 reps, touch/go or dead stop, you are strong. The problem arises when people bounce the weights - which means they aren't doing "touch/go".
In the end, do what thou wilt because the strong end up strong and the weak...well, they just debate over the minutia. Remember that and everything will fall into place. Diet, training, mobility....always look at the bigger picture.
