I think I'd fall into the engineer group. I don't go all out trying to get every bit of machinery I can but I use what is especially helpful to what I'm doing at the time. I also like working out ways to build auto harvesting contraptions and that sort.
Certainly enjoy the Magic side of things though and wish there were some good options for food, farm, breeding, and general "life" related mods. I would love to be able to play as if advancing through the eras (Stone Age, Bronze Age leading to Industrial and Future Age).
