Allbinos did test the Alpha Ultravids HD 10x50 in January 2010, of course that is well prior to the Plus of 2014
I understand that statement but it needs context to really tell the story.
Both the Leica Ultravid HD's in 10x50 and 10x42 out scored the Swarovski EL WB 10x42 in May of 2010 when these were compared by Albinos and they were then representing the respective companys' top Alpha glass in their resective categories. (Swarovski 10X50 have never been tested by Albinos).
Subsequently Swarovsky released their updated 10x42 EL Swarovision which out scored everyone but the EDG's. But we do not have any Allbinos' reviews on Leica's latest generation 2014 updated HD
Plus. The only direct Allbino's comparison we have is 2010, between the two company's 10x42 Alpha's and Leica won; and, Leica's 10x50's that same year scoring even higher than either 10x42.

So at this point a direct comparison from Albino's of the most current top shelf 10 powers are speculative and pending an HD Plus test, as well as tests on the latest generation Zeiss HT and SF for that matter. For a very recent alpha shootout (December 1, 2015) with all the company's latest stuff in 8x see
http://www.greatestbinoculars.com/allpages/reviews/shootouts/shootoutpremier8x42s/8x42shootout.html. And while that extensive comparison was seemingly more subjective than the Albino's scoring system; it is worth noting that this was a comparison of apples to apples, the latest and greatest from Leica, Swarovski, Zeiss (HT and SF), and Nikon; and Leica came out on top. That is merely one review but notable, and I would imagine I could be perfectly happy with five of the six binoculars reviewed.
