There's a fair bit on empirical and anecdotal evidence (if you consider anecdotes to be evidence) that the Watson packs are superior to the Wasabi packs. The Wasabi packs, likely being the most common, have the most written about them. The Watson packs seem to be a house brand of B&H, and B&H has a very good reputation. I am rebuilding some old Wasabi packs and testing one new one in the D-LI90 equivalent size. I have some used Watson packs on the way for testing in the D-LI109 equivalent size. Ultimately though, true quality can only be determined with real scientific testing, including multiple samples, controlled conditions, etc
