Part of the topic question is misleading; there have a variety of reverse holo styles, including minor variations seen from set to set. For my answer, I'll be going by card style or design, not the physical quality of the card (which may warp, based on the methods used). Images are on a hosting site, so as to avoid leeching bandwidth.
Legendary (WotC): The first design. Picture was non-holo, even if card was holo. Rest of it had that holographic pattern, including card borders. Attack text was a bit harder to read, especially if small, but I like the silver borders to the card.
Expedition-TMTA: Card has a slight gold tinge, no pattern, rainbow refractory appearance. The least interesting, only really good for showing where cards are damaged.
Hidden Legends: Only the picture was holofoil, had a background that displayed Energy symbols. A welcome change of design.
FR/LG: Smaller, more random Energy symbol placement is another design improvement, reminding me of the old holographic designs. The set symbol was added behind the text in holofoil, which as a Poke Ball looks nice, but might detract from reading the text.
EX:TR: Well, great. This starts the "list the set in the bottom-right-corner" trend I disliked about later reverse holofoil cards. Set name is in color for holo-cards (by set number), silver for non-holos. One thing I do like was how the card name on what would be normal holographic cards is now gold, although I don't like how the Energy pattern carries on into it. No more set mini-symbol in attack text area.
Deoxys: A very ugly reverse holofoil pattern in addition to the set symbol. Only the X is in color in Deoxys on non-holo cards. Worst type, in my opinion.
Emerald: Poke Ball and starburst pattern. The pattern on-card looks a bit pixelated, but it does have a few cool effects when tilted and turned in the light. Emerald is green on holos, silver on non-holos.
Unseen Forces: Absolutely beautiful. The reverse holofoil looks like normal holofoil, making for amazing rare, uncommon, and common cards. Set logo is much smaller and less pronounced, and there are beautiful 3D Poke Ball lenticular-like holograms in the background. My favorite version of the reverse holo, I would be happy to see these come back. Also, now any rare, holo or not, has the gold name. The only problem, as you can see in this picture, is that the revere holo lining doesn't end up matching card borders, leading to pronounced lines in the holofoil that look... not so great. Ones without this flaw are beautiful.
Delta Species: Eh... okay. The picture is a plain rainbow coating, as are the yellow card borders. Not as bad as some previously described, but a bit sparce. Set logo's getting a bit bigger again...
Legend Maker: Is essentially the holographic form with a DS-sized set logo, small circles and spirals in design. Even though it is useless, reverse-holo React Energy is still one of my favorite-looking Energy cards, coming behind the Emerald and Unseen Forces reverse-holos.
HP-PK: And we're back to DS-reverse holo design, which makes sense given that LM came before DS in Japan.
DP-on gave us reverse-holos similar to RS-TMTA, except without covering the card borders, which is a shame. Of all the reverse holos, Legend Maker, followed by Unseen Forces, would have to be my favorites, and it's disappointing to see the shift away from them.
