Mori is definitely a tier above you, I agree. Mori is an amazing player who almost nearly never mishammers. She makes amazing reads and is made great by her ability to constantly reevaluate reads and not ride them, almost always doing this to the benefit of town.
Were the old players with high win% like Fantastic, Rathwins1, Effulgence, Duckhunter that good? -They were really good especially Fantastic but none of them were as good as their respective win rates suggested, none could recreate the high win% upon returning on new alts.
