I've used MPH for about a year now and I've found it to be just about the best pool out there, I think lately the dev has not been so visable on this thread as he used to be but I guess the extra work he got from the NiceHash refugees has probably put a bit of strain on him.

I've mined ETN on MPH and not had any problems but I've move to mining ETN at https://etn.spacepools.org/ as I think it has a slight edge on MPH, this may be a false perseption but as it's working fine I've just stuck with it.
