They are both pretty darn good, but Earliglo wins by a nose... At least that was what I remembered from when we planted a few years ago. At this point, with all the runners they're mixed up and I can't really tell which is which. Jewel was supposed to be a little later, but for me they came almost at the same time.
The MdB are the best, but I have a much smaller productive patch that isn't mulched as has less sun so they're more likely to rot, get slugs, etc. Most of those are just eaten right away.
