What are the differences between the Dark Fiber Mines pools? ( Sorry, Im new to this)

I know that they opened a new pool about a month ago and I was wondering if there was an advantage or disadvantage to choosing one pool over the other. Im currently on what I believe is the original one (stratum+tcp://198.245.49.102:10008) running a single gtx 1080 at about 17MH/s, however I've noticed that the new one has more people on it. Why is that and is there any advantage to me switching to the new one?

Thank you.
