Depends. If fps lag isn't an issue then a BC pump is better. But if you want to avoid fps lag then use the advanced pump (it eliminates flowing lava blocks, getting rid of most of the related fps lag).
Just my 2 cents. I would go even more economical with 4 redstone engines and a BC pump. Use either liquiducts or the water pipe to connect it to either a liquid tesseract or an ender tank.
