Here are my Pacifism replays. I like how each style also has an identifiable puzzle style: the Sports theme resonates with the Lemmings Reunion Sports levels etc...
Some of the levels where I felt the leftover skills might be unintended:
* 05 6 Floater 3 Platformer 2 Builder 2 Fencer
* 08 1 Builder
* 25 1 Floater 1 Stacker
* 32 1 Walker 1 Floater
My favourite levels:
* 21 Little Wilma - One of the first of all these cool Cavelem style levels
* 27 Dr. Do-Ping's Hideout - I also like all your Sports style levels
* 39 Symphony Of The Night - a very engaging beginner difficulty puzzle
* 41 As Far As Peace Can Go - seemed very hard after the Pacifism levels, but didn't take long after playing some of the Neutrality levels as well as the NeoLemmix Introduction Pack
Least favourites:
* 26 The Circular Lemming Reactor - maybe I just dislike teleporters
Now a few more Neutrality levels to solve.. perhaps in the next weeks...
