legendary ore farm

Which is more profitable mine ore under productivity and speed beacons or straight with quality modules?

Once you have a few tiers of mining productivity research, the productivity modules pretty much lose their value. I don't think speed beacons make much sense either since you'll just drain the patch faster. You'll need to open the same number of ore patches in the end, with speed beacons one after another or without them in parallel.
