This pack is nothing short of amazing. There might be a few gripes here and there, but overall it shines as arguably one of the best tech packs ever. It creates an experience where the focal point is pure automation and base expansion, allowing you to create a megafactory of your dreams.
There is no bloat - every mod, quest, and automation process it asks for has or will have a purpose. Quests and objectives are often very clear and consise. The pack legnth is also very reasonable for an Expert pack - unlike it's GTNH cousin.
I heavily recommend this pack to literally anyone looking to embark on a long technological journey.

It's a decent modpack that you can have some fun in. It's use of trees, while unique, completely overshadow many other mods, and turn their respective quests (plus many more) into a boring slog that adds next to nothing to your playthrough. Has quite a few bugs and unintended interactions too, but funnily enough most of them end up actually being more helpful than detrimental. With a few pretty big exceptions...
