I like #evilwm too. Did not know much about #pekwm though. When I tried it in VM I was very interested in the grouping feature like what #haikuOS provides. But it required the middle-button click of a mouse, even my thinkpad touchpad middle button would not work. Since I rarely usually use a mouse and depend almost solely on touchpad and keyboard comes with a laptop, I did not go further with it.
