I generally now avoid BC in favor of RP equipment. Especially on tekkit, Buildcraft stuff can too easily lag out a server if a machine starts dropping tons of items due to pipes not checking for available inventory space. Now that there is an ATC replacement, you can pretty do any factory stuff purely with RP.
The only thing I still use BC for is the filler as it's very effective for clearing land and throwing up basic structures. I want to mess with the builder and blueprints this time around, too.
