WHAAAAAAAAAAAAAAAAAAAAAAAAAT!!!
Redpower is MUCH userfriendlier, than BC. The "Items do never fall out of Tubes"-Part is definetly userfriendlier, than "Spit all Items out, if there is no Space and cause massive Lag"! All the Stuff of Redpower does what it should do and nothing EXPLODES when wrong (or even when right!) used! The Logicgates are much easier to use, than the BC3-Gatethingies, and you can do EVERYTHING what BC3-Gates can do, with Redpower (except the Haswork-condition but it is Part of BC itself)!
I agree with the Documentation as the UNofficial RP-Wiki needs to be updated, and the Fact that Redpower has no Forum, but that has nothing to do with Userfriendlyness. Also Direwolf explained the RP-Stuff pretty good.
