So after a weekend of listening (as much as time would allow) I've found I can't deal with memory wire, I also do not like wearing my hp's wire up. So unfortunately the ATE-S and ZS1 are out for me.
When I did get a good seal, after many many tips, it just wasn't worth it for me...too uncomfortable. I did enjoy the sound of the ATE-S but the fit is just too much work.
If your looking for a darker sound and like wearing your iem's wire up then the ATE-S is a good option as long as you can deal with memory wire. The ATE-S do seem to have a bit more treble than the ATE and I liked the overall sound signature but unlike the original ATE you can't wear them wire down. I never warmed up to the ZS1.
Now on to the ED3 and ED3 youth...
