*Throws opinion into the ocean* I like variety, especially in a sandbox game. Dartcraft, for example, is almost entirely original. That's why people like it. It's new, fun, and has solid content. Thermal Expansion on the other hand, had me skeptical at first. Most of the content seemed like an MJ version of IC2. Once you start getting in depth in it, you find more content that's innovative and new such as conduits, liquid transposers, the magma crucible, the new molten buckets and such. The whole point is, people like new toys. Having mods that have nearly the same function is like getting the same set of Legos for Christmas. Sure you can do more since you have twice as many Legos, but the fact is they're still the same and they're going to grow old fast.
