I actually found the new mechanics on Fulgora and Gleba very enjoyable. Fulgora especially, for whatever reason. I enjoyed spaghetti-ing my way through all the planets by primarily using the resources available on that planet ("starter" rocket full of belts and power poles notwithstanding).

Aquilo is just so barren. The new mechanic it introduces locks down player choice, as opposed to the other planets that are rife with opportunities for exploration and creativity.
