Not to come off like I'm pimping Mekanism, which I guess I kinda am, but Mekanism really does have a lot of what IC2 and TE have, and then some. The coolest, most server-friendly, and efficient form of automated mining? Check. Ore doubling and tripling? Check. Machines with configurable I/O sides? Check. Colourable item transport pipes a la RedPower? Cheeeeeeck. The nicest-looking and (to my knowledge) most effective method of fluid transportation? Again, freaking check. Plus, its got universal cables, machine upgradability, the problems it had in 1.5 with AE have long since been fixed, and those most wondrous factories. I haven't even gotten into Mekanism Induction, yet. Mostly because I've not played with it, but it looks cool as hell.
