Learn the Brownie "Pop"
Faster than the emerson or an auto.
Opens upon clearing the pocket just like the emerson but you aren't relying on the crutch of the "hook" to grab your the back of the pocket as it goes by which could be missed [though unlikely, it does happen under induced stresses during training sessions.
It is one of the fastest to open from pocket unless you have trained to pop them as all my students can attest.
Yes, it's takes practice, but then you don't have the crutch to rely on. I'd rather rely on my own ability than a gimmick, but for those who refuse to train religiously on their presentations from pockets it is the next best thing I have found to date.
One of my students had the enerson commander and was quite fast with it, thought actually it would be faster than my "pop".
He now uses the pop and no longer carries the emerson as he no longer needs the crutch.
It's alll in the technique and practicing it until it is second nature. Doesn't take that long either, ,maybe a couple of hours tops but I have had students do it within minutes.
As well, if you know the "pop" you can carry any combat folder and produce the same results. You aren't limiting yourself to the one or two designs that have the crutch [hook].
Brownie
I can see how that can be tough on pockets 
So it's actually open before it's completely out of the pocket?
