Seems you already made up your mind, but my $0.02
ECS wear very quickly. They kind of have a dual compound type nature to the tire which is grippy at first and wears off rather quickly as you go through the tire. I noticed considerable differences even before the D/W started to wear away...
PS4S is substantially quicker in both dry and even quicker in the wet. The compound lends itself to blend drying conditions quite well. Only real instances where ECS is quicker in the wet is if you're in monsoon conditions and have standing water where tread void wins over compound. PS4S will hydroplane in these instances however recover really well when threshold of grip is exceeded/comes back.
ECS in the wet is more of a snappy type feel where the tire simply lets go, PS4S in the wet is like a street tire in the dry. You kind of just start losing grip and you begin to notice - however recovery time is pretty amazing where the grip just comes back if you back off 10%
I don't think you went wrong, both have their strengths. You may find the ECS to be a bit soft sidewall wise. Sizing the PS4S to 225s I think may have actually paired real well with a 17x9 tire. That tire tends to chunk shoulders if you try to push it too much.
