I have been using Yabai for two years now and am very happy. For me, it's stable and you can script almost anything by using event reactors.

Yabai also makes working with a 15" display much more productive imho. For example, I can effortlessly and nearly instantaneously switch between browser and coding spaces by pressing hyper + w / hyper + c (I'm using Karabiner Elements to map capslock to hyper).

Since it's a common misconception, you do NOT need to disable SIP if you don't care about some features (noticeably, disabling those nasty space switch animations). For an overview of features that require SIP to be partially disabled:

Also in general, the wiki on GitHub is very well-written.
