I like Psi balance. Early game it's a go-to do-everything thing that lets you avoid vanilla tedium while other mods catch up. Mid-late game it's a fine tool that lets you do specific things not covered by other mods. Like placing and removing blocks in specific way you need, doing things with mobs in specific way (smite pig to turn it into zombie pigman, then Add Motion it to cage for Intangible). I carry two CADs (one in bag), because I can't fit all things I regularly use in one. Psi has a niche of portable fine-tuned automation, and has no alternatives there.
