Opinions on the Different Pipes?

I'm getting back into minecraft after a several month hiatus, but as I sort through the different mods I can't help but feel conflicted on which pipes I want to use for my tech mods.

I know EnderIO allows liquids, solids, and energy through a single block. Buildcraft pipes are still around, but I'm not sure how they measure up to the others. Thermal Dynamics looks neat, but I've heard they're resource and time intensive to make. I've always liked Mekanism pipes, but I'm not sure how they measure up to the others either. And then I see there's a mod that's almost strictly pipes called Refined Relocation.

What are your opinons? Which ones have faster transfer speeds, are easier to implement or upgrade, or have lower resource costs?
