I think it's really interesting that people think RP2 tubes are "more powerful" when pre-Sortron Buildcraft actually has much more powerful and programmable logic. And the Emerald Pipes can be really, really, really powerful.
What I think Buildcraft really lacks is some sort of conditional routing tool. If it has that functionality, I sure can't figure it out. Like, for example, a gate like the diamond gate that instead of routing on item type can do direction selection based on pipe wire signals. Because the main thing that BC can't do easily is route a 1-to-many fanout of machines without an intervening chest, whereas RP2 is so good at this that you can actually make cyclical networks and so long as the restriction tubes are put in the right place it'll still work.
You can do it in BC with a chest: you use an AND gate to detect an empty inventory on the target and a clear pipe and emit a pipe wire signal to the chest (1 pipe away) which will pull from the chest if the pipe is clear AND the pipe wire signal is set. But this is obviously awkward and very slow due to the traversal speed of extraction pipes.
I really wish that someday we'd get a "sorting gate" that when placed on a junction pipe could make routing decisions. Pipe wire is so cool, but it has only very elementary applications and due to the slow speed of pipes it almost always lets items drop.
