Not really, except that maybe cactus is more accessible and is pre nether.Is there a benefit to cactus over nether wart?
This is also a better option. But adding an extra harvester to sheer the leaves just moves the build complexity to MFR instead of Thaumcraft. Then again Thaumcraft things are a little bit of a pain to build in comparison to MFR.I just use leaves from trees, as they only give herba and nothing else, so no need for over complicated setups.
you could build 1 large tree farm with 2 harvesters with 1 harvester set to collect leaves, or build 2 small tree farms

I know it's not "complicated" just as setting up an essentia centrifuge and void jars isn't complicated. I'd still opt for the method you stated though.it's not really that complicated... just plunk down another harvester and hook it up onto your other harvester's system
heck, you can even just use your normal tree farm if you already had it set up and just teleport the leaves to your essentia system
