The back of Single Lenti is nice b/c that's unique but the front has been used by both U'mania and HDZeta for lenticulars so far. I would usually go for a 4K release but liking that both Aquaman and Mera are on the Double Lenti so might go for that and pick up a 4K disc later.
It seems like WB/DC is starting to get like Disney in that they are limiting what can be used since between the three different releases, there is a lot of repeats of artwork. Honestly I like HDZeta's 4K Lenti slipbox the most because both sides are unique but not a fan of the posters instead of a booklet or of the atual steelbook
