For any vanilla resource, not even bees can possibly compete with Magical Crops. Magical Crops are also compatible with MFR, so infinite emeralds, diamonds, vanilla ores, ender pearls, blaze rods, etc, are only an MFR farm away. You do have to mine your first bits of essence to make your first seeds, but harvesting a Magical Crop has a chance of giving a lesser essence. Those little things add up fast when you're harvesting a 25x25 farm.
So get your Fortune III pick and take 10 minutes to mine a couple stacks of essence, then profit like it's 1999. Wait...profit, then party like it's 1999.
